I would definitely have to agree. With some of the other people on here, GM needs to do a recall on this problem. It's obvious there is a major flaw in the car.

I have had the car towed 4 times and sent to the dealer twice. It is still at the dealer and they have had it over a week. They have replaced fuel pump twice and it still won't work. It will work for them but when I get in to start it - it won't start. They say nothing is wrong but when I try and start it it won't start. This needs to be recalled. With all these complaints about the same thing I don't understand why GM won't recall to fix the problem. They should stand behind what they make even if they don't make the model anymore. Will not buy another GM product.

Ok, I have been dealing with this problem for about 3 years. I had a solution that was working fine until today. In the past, I had turned my key to "ON" position until the security light stopped flashing which usually took anywhere from 7-10 minutes. Once it stopped, I would turn the car off then crank it right up. Well, that didn't work today. The security light started flashing and the car didn't' crank after 15 minutes. I tried several times to crank it but it wouldn't. I called a repair shop and they sent a wrecker to get the car. The guy tried and it almost crunk up, but of course, almost doesn't count. I have no idea what is wrong but I'm stranded without transportation once again. Someone, please, send me some advice because this is getting really expensive and tiresome.

I am very amazed how everyone is experiencing the same problem? This is absolutely ridiculous. Basically, let me give you an overview of how I treated this car since day 1. I purchased this car for my girlfriend who is now my wife back in October 2000. It was a brand new 2001 Alero GLS fully loaded. Only 2 miles on the odometer. I have babied this car since day 1. I've ran nothing but Mobil 1 Synthetic since it's 1st oil change after the dealership til now. Every 6 regular 87 octane fill ups I always use Mobil 93 Octane once. The first time my wife experienced a non-start was when the car was 2 years old and it only had 9,000 miles on it. We really paid no attention to it... at the time. I had a buddy of mine who's a mechanic... change the battery, alternator, spark plugs at around 26,000 miles and it was about 5 years old. We would experience LONG start ups. Usually a car turns over quickly... this Alero takes like 10 seconds to turn over. Cut the story short... the car is 8 years old now... 38,500 miles on it... and it is stuck outside on the road at a family members home... PROBLEM... The car won't turn over!!! The battery tested good and the alternator tested good! General Motors has a very serious issue on their hands and they won't listen to us! I have babied this car since day 1... and I feel like I babied a LEMON! Wish you all the best in fixing this problem... I have no idea what could be the cause of this ridiculous nonsense.

I bought this car used in late August 2007; with 25K miles. It is currently February 2008, and this car has been back to the dealer 5 times now for the same problem. I bought it from a Toyota dealer and apparently the previous owner traded it in to the dealer I bought it from. The car just would not start, from time to time. No reason, or explanation. The Toyota dealership I bought it from sent it down the street to the Oldsmobile dealership. They told me they previous owner had the car there for the same problem. Each time I received the car back they either said they could not find a problem and it just started right up. Or they found a problem with the fuel pump, then the security device. They claimed the car was fixed. But the problem still persisted. Without warning the car would not start, causing me to have it towed. I am at my wits end at this point ready to get a lawyer. I truly believe this car is a lemon!!!!!!!!!!

Well, sadly, I took over the payments of this car from my parents. I wish I had done my research. In the past i remember hearing about the car not starting and problems with the security light. They took it in (GM dealership) and like everyone else they couldn't find a problem. They did end up changing/replacing a few things on the car but I cant recall as it wasn't my car at the time. About 4 months later it happened again. Towed it, took it into the GM dealership and couldn't find a problem. After having the car for a couple of days they said the problem came when the gas cap on the car was on properly, therefore throwing off the computer and fuel system. They said make sure its on tight and properly and after driving it for awhile it will go away. It worked! and hasn't had the no turn over starts, BUT will get the occasional start that takes a few seconds before it fires. By reading all these complaints and other sites, this is what I've found out.
Possible Fixes
1. Fuel relay switch (fuse under the hood) just replace.
2. Ignition fuse
3. reset the computer (passlock reset i think)
- Turn off the car
- Turn to 'ON'
- Security will flash (if it turns off, its not a passlock problem)
- wait 10 min, light will go on steady and then will go off
- turn key to off and take out key
- wait 10-20seconds and try to start.
4. Try to start in neutral (dont ask why but i hear it works)
5. MAKE SURE WHEN YOU FILL UP YOUR GAS CAP IS ON PROPERLY!
Possible Problems
- Crank sensor
- Oil pressure sensor
- cam sensor
- Passlock key assemble
- fuel pump relay
By the sounds of it is a computer/fuel system problem. This 'anti-theft' system i think causes more harm then good. I hear something as simple as someone trying to lift your doorhandle when your car is locked can manifest this problem to not having the factory key chip when you start your car can 'confuse' the computer. I think its such a wide range of problems that cause the car not to start, not just one simplified problem.
When you go to start your car turn to 'on' and wait 5-10 seconds and give the gas pedal one quick pump and then start your car. This has helped me a few times.

It was 'bad' gas. Oddly enough our neighbor has an Aurora and he had the same problem, so he told us to try draining the tank and refilling with 93 octane, and using gas treatment. It worked. I have bought gas at the same place for 10 yrs, and never had this problem before. And I was without my car for 4 days while we tried to determine the problem. Definitely a huge pain in the ass.

Engine turns over, but no fire. Was a real mystery for a while. Seems that if the fuel level drops below 3/4 of a tank, it will not start if left for more than a couple of hours. Keeping the fuel level above that, I have not had a problem starting. Not a solution, but it seems to have worked for the time being. Bit of a pain not having full usage of the tank, but works fine on long trips as long as we fuel up before shutting it off.
It sounds like none of the other solutions have had much success, and have cost a lot of money.

RMPS way up on ocassion. Will not reve down until you turn off the ignition and restart. The starter will not turn over in park. Have to start while in neutral. The cruise control button suddenly stopped. Fuel filter replaced. The problem with the starter appears to linked to manually locking versus remote locking.

This is a serial problem with this car. GM knows this is a big issue with this vehicle, but will not recall it. I have had this problem happen on 4 different occasions within a year. And they wonder why GM has gone to hell in a hand basket. As much as I wanted to stay loyal to American made, at some point enough is enough. You gotta buy foreign and lose the headaches, agony, and added cost.

Hello fellow 2001 Alero owners, I purchased my car in 2003 and the problems have not stopped. I have taken the car back to the dealership at least twice a year, 6 this year (2007) alone because it will not start, only for it to start for the mechanic (really embarrassing), I have had the fuel pump changed, along with the battery, I have taken it back to the person who has installed the alarm system only for them to tell me that their device will not effect the car manufacturing. Currently the mechanic is informing that the valves that pump the fuel into the engine are locked open and that they have been flooding gasoline into the engine now I need a new engine. Since this has happened so many times and from reading all the other complaints I'm not sure if the engine is even the problem. But I am willing to participate in a class action suit.

hello i wrote before telling everyone to Call in to GM. Well it was a waste of time and pissed me off even more. They basily said nope you did not buy the car new and you did not bring it to a GM dealer. so Your Shit out of luck. Like i want to bring my car to a GM dealership and pay $500 so they can open up the hood and say yep you got a problem. No I will never buy a GM again. No wonder why they dont make these models anymore. Maybe GM should have put more into their cars not paying all this money to have their cars turn in to Bumblebee in Transformers. Also visit the other sites that all of us Go to tell GM to Screw off.

I was home from school for Christmas break, my mom and I were shopping for some last minute gifts. The car was running great up until we got home. I had to go to work, so I go out to start the car and it won't start....... it would crank all day, but it would not turn over. I had to have it towed to the mechanic. I have had this happen many times already...... I have replaced the fuel relay switch, the ignition switch...... TWICE....., something else to do with the fuel system that wasn't cheap, and now the fuel pump. I have had my car die in the middle of traffic........, I have been stranded more times then I can count..... and on top of all this, I took it to a dealership here in Bloomington and the mechanics couldn't find anything wrong with it (thinking I was just some stupid girl who doesn't know how to start her car), so guess what, after driving it back home it wouldn't start the next day. It seems that anything I get fixed that is "causing the problem" fixes it for a month or so but then pretty soon something else seems to be causing the same problem. I think that something in the computer system of this car is causing the parts to go bad...... one at a time..... I wish there would be some type of recall or that they would find a solution to this problem!!!!

have a diagnostics run on the car by a mechanic, the cam sensors ave been know to go bad but no recall has been made. I'm thinking at 30.00 dollars a pop to fix it plus time at the shop and having to have the computer reset so the car will run, there should be a recall. I had problems not related to this already with my car and have had it with these models. Don't get me wrong I love my car WHEN IT RUNS!!!!

The mysterious "Tries But Won't Start" syndrome struck my 2001 Olds Alero this summer.
Occurrence #1: Stranded me at the office after working late. (I knew I should have gone home earlier!) Towed the car to the mechanic and was informed that the fuel pump was bad and needed to be replaced. Cost: $700 + 2 days of no car.
Occurrence #2: Three weeks later, I was stranded alone on the road in rush hour traffic three hours from home on Friday evening of a holiday weekend. It took 2 hours to get a tow truck and to find a garage that could look at the car before the end of the next week. We had the fuel pump relay (provides power to the fuel pump) replaced. Cost: $200 + 3 days with no car + having my spouse interrupt his vacation and drive 5 hours one way to pick me up + having to make an additional trip to pick up the car.
Occurrence #3: Less than two months later, stranded at the office. Again. Had the car towed back to the mechanic's shop. They replaced the fuel pump again (luckily under warranty from their previous repair). The mechanic informed us that there is a significant issue with GM fuel pumps and they typically replace 40+ per week.
Occurrence #4: A few days later, the car dies again at the office. This time, when the mechanic ran the diagnostics, he said that, in essence, my car forgot its password. When the passlock system forgets the password, the computer assumes the car is being stolen and shuts down the fuel system. To reset the passwords, you should turn key so the car is running on battery (radio will be on, but no ventilation) and wait 10-15 minutes. The security light is supposed to go off and then you should be able to start the vehicle.
Occurrence #5+: Wouldn't start to drive to work. Reset the passwords and it appears to be running ok, but the security light will not go off. I'm concerned now about my battery life with these frequent resets.
I say a quiet prayer every time I try to start my car. We're shopping for another car, but I hope this one will hold out until we find one!
I'm now finding that this is a very common Alero complaint. (Also check out the edmunds.com CarSpace Town Hall postings for lots of information.) The PassLock system seems to be more trouble than it's worth!

I purchased this Alero in July 04 with 58000 miles on it. It now has 147000. two weeks ago it left me stuck about 65 miles from home because it would turn over but not start. It was 5 on SUNDAY! I did not want to have it towed to my house, as that would have cost a fortune! So I found a mechanic in the area and was able to rent a car from them as well. They called Monday morning and said my positive battery cable was very corroded and must be replaced before testing can occur. OK I said to the tune of $195.00 then they called and said my battery was not putting enough amps out to run the test and that it needed replacement. BUT, I could bring my own if I wanted. Theirs was $95.00. (again, I don't live near there so said just put yours in) after those two replaced, they called and said they found the problem. THE ignition fuse was blown,$2.36. YES I SAID TWO DOLLARS and THIRTY SIX CENTS!! so after towing, car rental, diagnostic and repair parts and labor, I spent 579.00 FOR A FUSE! I hope this helps someone!

For the second time in a year, my car won't start. It turns over but won't fire. First time it left me stranded in the grocery store parking lot, cost me a tow truck, 3 days at the shop to get the problem diagnosed and then $750 Canadian to fix. They said it was a computer component that had to be replaced (took them two trial and errors to figure it out). Three days ago it happened again. Now the car is sitting in my garage and will have to be towed again. It was running fine when I parked it, and the next morning it wouldn't start so there is no "lead up" or indication of a problem beforehand. If it turns out to be the same problem again, I'm going to dump the car and buy a bike!!!!! If anyone has a permanent fix for this problem, I would love to hear it as I am at the mercy of the mechanic every time.

On a day of a big professional exam, this very stupid defect chose to manifest itself. When the repair shop told me how much this was going to cost and what they had to do to fix it (basically disassemble the dash and replace the ignition cylinder and tumblers (although most service people consider tumblers optional)), I had a cow.
I really wish I had found this website first and hacked it as suggested in this forum. This car is practically not worth anything anymore.

Okay I am really upset.... my car has been sitting in my garage since November. Everytime I try to start the car the engine cranks but the car doesn't turn over, I took it to the dealership and they had the car for a full day and they insisted that nothing was wrong with the car..... I bought a new fuel pump because everytime I placed the car in the on position and heard the fuel pump buzzing or connecting then the car would start, but if I didn't hear that then the car wouldn't start so I figured that was the solution (a new fuel pump) and it worked for about 2 weeks... I had the ignition switch replaced and and it worked for another week and then it went back to cranking but not turning over. I am so fed up I am ready to just get rid of it and buy another car. I am sick of American made cars they are nothing but trouble. Can anyone help me!!!

I always have trouble starting the engine only when the engine is warm. It either cranks and doesn't start, or when it does, the rpms are too low to maintain idle. I have had 2 gm dealers look at it. The 1st
place tried a software update. the second replaced the fuel pump. neither one corrected the problem. I have found if you turn the ignition on, but wait 4-5 seconds before cranking the engine, or push ing the gas down slightly while cranking the engine will get it to start easily. I may try a fuel pump relay or a fuel pressure regulator and let you know if it helps. cleaning the fuel system and replacing the filter had no effect. Dealerships act like they've never heard of this problem.

OK sounds like we all have the same problem I have been searching online & found a great piece of advice from another web site here it is: Is your security light flashing? If so, leave the switch in the on position for 10 mins. until the light stops flashing. Then try to start your car again. This problem can be intermittent, but will usually get worse and be extremely inconvenient. Sounds like the typical Passlock II defect in the Ignition Lock Cylinder. A dealership will charge about $450 to replace it with another defective part. GM will never own up to the defect.
My security light started coming on again about a year after paying the dealership $450 to replace a faulty Ignition lock cylinder. I was at my wit’s end. My wife and kids would be stuck at night in some shopping center parking lot waiting 10 minutes to reset the stupid thing. I was able to Bypass, Disable or Ghetto Hack my passlock II anti-theft system on my 2002 Oldsmobile Alero without relays or resistors. I had my local Auto wiring tech install a $5 on/off toggle switch under my dash that is connected into the yellow (key resistance/code/recognition) wire that can be cut while the engine is running to essientially bypass passlock I(1) or II(2) permanently.(I do not have nor intend to install a remote starter and I do not have an alarm on this car.) The toggle switch idea came about because of my concern that a dealership tech could possibly reset the security “fail- enable” mode or the battery could die or become disconnected for an extended period of time and reset the intended fault. All I need to do is flip a switch to break the circuit again while the car is running to take the passlock system offline. When the system is offline, the security light is on constantly.(Not flashing.) I don’t mind the light, but others may want to remove the bulb or black it out. Here’s how the setup works:
1)Switch On while engine is running – Security system is on.(Factory Setting) Security light is off. (Circuit is complete.)
2)Switch Off while engine is running – Security system goes into “fail-enable” mode and bypasses the passlock system.. Security light is illuminated.(Circuit is broken.)
3)Switch On while engine is off – Security system is on (Factory Setting)
4)Switch Off while engine is off – Security system detects this as a theft attempt
and will not allow you to start the car until you flip the switch On to complete the circuit.(Acts as a FUEL KILL SWITCH.)
Below you will find a thread and some supporting evidence of why this bypass actually works. The entire job took 25 minutes. There is an incredible link below with high resolution pictures of the wiring for your specific car. I included the actual photos that I used to gain access to my ignition lock cylinder wiring. *Special note: those with GM Class II Data Bus should leave your radio connected during the entire procedure so nothing weird happens. If you are unsure if your car is so equipped, it’s best to leave the radio connected and let it hang. Good luck and post with your success stories! 12/4/05
http://www.the12volt.com/installbay/forum_posts.asp?TID=59694&PN=1&TPN=1 Is this You? Get in your car....try to start it and find that the passlock II is screwed up again, you have to wait 10 minutes for it to reset. When it resets it starts up and runs fine. Fix-------Start the car, find the yellow wire that I'm sure you've read about, the rcode wire that is, and cut it. Shut off the car and you're done! The rcode wire on my 2001 alero is behind and to the left of the radio, you must take out the radio.....the yellow wire accompanies two other wires, the white and black, the 3 wires are alone and run inside what appears to be a cheap electrical tape that will fall apart in your hand when you start tugging on it, they are very thin wires, maybe 18 to 22. I taped off both ends of the yellow wire too.Took me about 14 days to find this out and reading no exageration 1000 posts. Forget all the relay, DEI and resister crap that I'm sure you've read about. All this writing assumes that this will continue to work.....i WILL be back here to post an update if it fails again. If you have doubts of me coming back to update a failure you can email me
http://www.insurorsservicebureau.com/ISB%20technical/ISB_QA.pdf page 4, The PASS Key Module also has the ability to allow engine operation if it recognizes a system fault in the ignition key reference circuit while the engine is running. In this case the Module enters and remains in a mode which allows the engine to be started and run without reading the resistance chip. This mode requires that the original factory resistance chip key be in the ignition lock cylinder at the time the fault occurs. During this mode, the security light will be ON all the time. When the key reference circuit is repaired, the module will automatically reprogram itself to the mode requiring the original resistance chip.

The “Security” light may turn on to warn of a system malfunction, but even if it doesn’t, a key recognition circuit failure with the proper key in the lock will cause the TDM to enter what GM calls a “fail-enable” mode. Essentially, the theft-deterrent system goes offline and the engine will start and run with any key that turns the lock.

This problem has happened and left me stranded 15 times. For awhile I thought we had the problem under control, by not using the factory key it wouldn't trip the security and I didn't have the problem of it not starting, but of course, it came back. To make it worse, since I am not using the factory key, I was unable to reset the security device and thought it was another problem. After having it towed to my mechanic, and he was unable to get it started, my husband took the factory key to him and it started right up. That only ran me another $90.00, and almost caused me to miss getting my daughter off the bus. I feel this is a factory problem and the car needs to be recalled and fixed!!!!!!!!!!!!

I would like to maybe help some others on this site. I have not heard anyone trying this. I had my car for 8 hours at the dealer. They told me there was nothing wrong, well, it kept getting worse. I took it to my local Meineke shop and they worked on it all day yesterday from 9 to 4. They would not give up. He changed the "crank sensor" and that seemed to work yesterday. I am hoping this might help someone else.
I will see if this corrects it!!

Have had my Alero in two different shops and each time they tell me now they have the problem solved. Engine turns over but will not start. GM manufactured a car that is absolute junk. In my opinion this is why they phased the Alero out! PURE JUNK! Over the 5 years I have had this car it has done nothing but cost thousands in repairs!!!! I will never buy another Oldsmobile in my life!
UPDATE: It was the fuel relay switch. It was shutting off the fuel to the engine. $20.00 part but they hooked me the standard shop fee of $90.00 to put the part in. Next time I will know how to do it myself. It is located in the fuse box under the hood. The diagram on the back of the lid tells you which fuse is which. All you do is pull the old one out and put the new one in.

Leave car for two days it will not start again. Not sure if alternator is draining battery or if its electrical. Noticed rear light out and front light out. Car was repaired 6 months ago by dealer for a wire that the power steering hose had rubbed against and wore through. Anyone have anything similar, car has been parked for a week now afraid to take it out.

I just bought the car over the summer to go back and forth to school.. and this problem with not starting just started happening about 2 weeks ago.. as soon as the cold weather hit.. my father is a mechanic and tested it and said it was due to the electrical security hook up or something along those lines.. but I agree they should recall these cars and fix the problem.. not everyone can afford to spend hundreds of pointless dollars on other parts such as fuel pumps, batteries, and what not.. for something that the company is responsible for. I'm tempted to start looking into a different vehicle that is more reliable.

Alright, really mad about this one! bought the car from a used car lot with 68000 miles on it, thought oh yea 2001 with 68000 miles for 5 grand pretty good buy. well about a week later the temperature sensor went out so i thought no big deal and went and had it fixed. well after i got that fixed i noticed it was shifting real hard and the check engine light came on so i went and had that checked out. had some bad wires to the iat sensor so i thought okay and got that fixed no problem. well then a couple of days later my girlfriend goes in to labor and we went to the hospital, well it had sat for a couple days and when we went to leave it almost didnt start. i finally pumped it a couple of times and it started. well now today i went out to start it and it wont start at all turns over but wont start. i let it sit for a couple of hours still wont start and i dont know what to do im buyin a house so i have no money to fix it and im just pissed off.

I could not start my car after I was finished work. I was in a rush to get home, but my DAMN car wouldn't start. It is done this before in the past, but it always started on the second try. I tried quite a few times, letting it rest in between. So I had to ask a stranger to help boost my car because I assumed that it was a battery problem.
I then types in the problem online and of course everyone seems to be having this problem. I am very surprised that GM is not doing anything about this. I will be checking to see if my vehicle is still under warranty, and if it is, I will get it fixed of course, but I will be making one hell of a stink! This is complete bull. We pay a lot of money for our vehicles and the company doesn't seem to care! What is up with that. This will definitely be the last GM vehicle I will every buy and I will be sure to advise my friends and family of the same.
This is really bad customer service! What would happen if someone needed to get to the hospital and they lived in the middle of nowhere, and their car wouldn't start. Is that what it is going to take for them to pay attention?

If only I would have read these comments before I spent $400 on getting a fuel pump changed for no reason! I had this problem with my car not wanting to start, took it to the dealership, and was told it was the fuel pump. The security light kept coming on and on yesterday, I tried leaving and had the same exact problem. Now my car is in the shop again today. I'm not sure what's going on with these vehicles but something really needs to be done.

Man I hate this car, I have been left stranded so many times by this pile of crap. I have had it towed 4 times now fixed wiring, key switches ect ect ect has anyone thought about getting all of us Alero lovers together with this same problem and start a class action suit against the manufacturer. This is obviously not an isolated incident and there should be a recall and pain and suffering and I mean suffering. I have heard there is some way to reset it with the key in the ignition but the dealer won't tell you how. they want your money.

This is a followup about my starting problems with the Alero -- engine turns but never starts. The fuel pump was good; the mechanic changed something relating to the "oil pressure switch" It was about a 30$ piece. But in addition to the time it took to investigate the problem, and the tow, it rang up to over two hundred dollars. Hopefully this fixed the problem. My fingers are crossed.

I just purchased this car last week on Tuesday. On Thursday it turned over but wouldn't start. I waited for a little bit and it did end up starting. It did it later that evening. Took it back to the dealer I purchased it from on Friday. They had it and said it would always start for them and that they were keeping it until Monday. I picked the vehicle up first thing Monday morning and they said they replaced the Fuel Pressure Regulator and were confident that this would solve the problem. Took it up the road to a gas station 10 miles and when I got back in it did the same damn thing!!! After waiting awhile it started though. This car has 44,500 miles on it and is nice other than this problem....... after reading everyone's complaints I wish I never would have bought it. I wish I knew about this website BEFORE I made the purchase.. I will sure use it in the future. And was there a recall on the turn signals?

Usually, this problem is caused by the computer cutting power to the fuel pump because it thinks its being stolen. If you had a remote start installed make sure the bypass module is not interfering with the keys turnover reporting to the computer. We have a 2001 alero and a 2001 malibu that occasionally does this. I know its from the bypass module, but I want to keep my remote start so I deal with it. It is also most likely a faulty read output from turning the key. If the car cranks but doesn't turn over, turn the car back off. Turn the key to on, notice the security light will flash (if it goes off right away it is not passlock). Wait 10 minutes the light will go to steady on, then it will shut off. Turn the key off and take the key out, wait 10 seconds. Turn your car to start and that will get you going. Any GM dealer can read the codes from the computer to tell you whether its the key, or strickly related to the fuel pump.

This Damn Car... The problem started the day I brought it home from the used car dealership. They came and got it and it started right up. They did not mention what they did to fix the problem. About 6 months later the car wouldnt start again, would crank but not start. Had my uncle take a look, he released the fuel pressure from the test port on the engine. The car started right up. On August 29, 2006 wouldnt start again. Started by releasing the pressure, didn't work. Thought it might be the fuel system. Changed the fuel filter in the heat of Texas mid-day, Didnt start. Pressed the panic button on the alarm and it started right up. Now, a week later it will crank but not start. I cant understand it.

Same issues for past 2 years, cranks but won't start. Have replaced fuel pump 5 times, the fuel relay switch once, sometimes it just starts again after sitting for awhile. Finally took it in thinking fuel pressure issues, alas no, fuel pump is fine. Dealer says first of all our battery is too low, so our security passlock is losing it's code and doesn't recognize our key so won't start. A new battery will help, but will happen again he says. Need to replace to pass lock key assembly and then have it recoded to our key. To the tune of $365+tax. I guess this is the next step. AARRGGHH!!! Will let ya know!

Ok... I see I'm not alone. 2001 Olds Alero will turn over but wont start. Had it towed to the garage... they had it for 4 days. First they said it was the fuel pump... although I knew it wasn't. It was getting fuel and spark so they spent a whole day putting in a new fuel pump and then took it out when they realized that wasn't the problem. Then they put it on a scanner (so they said) and told me it was the computer module.. OK im ready to pay over $1,000 but when i picked the car up they said it was the fuel pump after all and that they had put a bad one in previously. $603.00 dollars and 7 days later.. my car is sitting in my drive way... not starting. Did anyone ever come up with a solution to this problem? HELP!

Same problem. Wife bought car in 2003 and had the starting problem. Would turn over but not crank. Dealership could not find problem, but it just went away.

Same thing. The car won't freaking start. Turns over, but won't crank. Very wierd. I started by replacing the camshaft position sensor. Sweet! my car runs again. But only for a week. Then I replaced the crankshaft position sensor. Sweet! My car runs again. But wait... only for a freaking week. Now I'm pissed. So I haul it to my Uncle's house. He's a damn good mechanic. He can help. Well he can't seem to get it to stop running. So I drive it home. Next day, dead. So I tow it to a local mechanic and pay 600 big ones to replace the fuel filter and pump. My car runs again. But only for about 24 hours. Needless to say it's at my uncle's house again. He thinks it may be the oil pressure sensor. If it goes out, the computer thinks the pressure is low and shuts off to keep the engine from overheating or blowing. It seems too that maybe everything that goes wrong with this vehicle is causing it not to start, so there may not be one sole solution. I will report back with the results when I have my car back.

Bought the car used. Almost immediately noticed that the engine would turn too long before starting. After about a month, it wouldn't start. Like it wasn't getting gas. Replaced starter. Replaced fuel pump. Replaced battery. GM was actually rather nice about paying for the repairs even though the car was technically over the warranty (by a few weeks). Note, the dealer wouldn't hear of extending the warranty, and said GM wouldn't. I had to contact GM myself (bypassing the dealer) to get the money.
In any event, the car started OK for about 1.5 years; OK meaning, it started, but not confidently. Today the same problem has resurfaced: the engine turned but the car wouldn't start. And so I was stranded. The mechanic arrived to give me a tow and on the spot he said he thinks it's the fuel pump. Again? I told him about my past troubles and he said he'll investigate. This is a major issue.

This car has been a pain in the ass for some time now. It started out with the turn signals not working which were finally fixed once they issued a recall. During the same time the cruise control button stopped working. I actually have to hold down the button in order for it to work. What's the point of cruise control if I have to do that?? Then finally, the darn car stopped cranking. It turns over but never fires up. For four days the car would not crank up, had a diagnostic test done and it found no defects. On the fifth day, I had it towed to another GM dealer and as soon as the mechanic turned the key it fired up!!! I was pissed. He told me that it was the security alarm that was causing the problem. He said most likely someone had pulled the door handle and triggered the anti-theft system. When that happens, it stops the car from getting the gas needed to crank up. He also suggested that I make the alarm go off and use the keyless entry to turn it off if it should happen again. Well, it happened again, I did what was suggested and the darn thing still did not crank up!!! Replacing the fuel pump and fuel fuses didn't work and ignition sensors appear to be fine. Obviously, there's more to the problem and no one not even the manufacturers know what it is or how to fix. So, if anyone out there have any suggestions please pass them along this way b/c I am too tired of giving the dealership money and them not giving me a working solution.

While attempting to start the vehicle. The damn thing would turn over but not start, and when it did the rpms would be too low to bring it up to idling speed. I personally think that it may be a fuel problem. I've taken it to a couple of dealers but to no avail. So really there has been no remedy to my problem. If anyone else has had this type of problem or knows the solution, I would appreciate your comments.

First let me say this. I am sorry for calling my wife a lier. LOL. She has missed work several times because the Alero wouldn't start. I would attempt to start the car later in the day and it would start right up. This happened over the last several months. And I was thinking to myself she was just lazy and didn't want to go to work.
We packed the car up for vacation and all piled into the car for vacation. I went to start the car and it wouldn't start. I looked around the engine compartment for a bit and took off the air cleaner. I had my wife start the car while I sprayed carb cleaner down the throttle. The car would run on it but would die when the stpray ran out. I switched the relays out and still no start. I also checked all fuses and no luck. So I assumed it was the fuel pump and we took my Sentra on vacation.
While on vacation I ordered a fuel pump on line so it would be there when I came back. When we got back sure enough the fuel pump was sitting on the porch waiting to be installed. I am so glad I went to work and did a search for Alero problems and came to this website. I followed the 10 min with the key to Acc, removed the key for 10 sec and attempted to start. It fired right up. I am only out $40 for the pump but I can't believe a manufacturer would install a system on a car that does not work all the time. It is like not doing your homework. I feel real sorry for the people that did everything to get their cars to start before someone figured out the passlock system was at fault. Thank you all for writing this down so I didn't have to go through the same thing you all did.
