They found rotted fuel module and hoses, removed fuel tank found fuel sending unit rotted, lines and hoses..replaced sending unit lines and hoses.

I notice a strong gasoline smell at first, then a large amount of gas became evident at idle in the driveway. I took vehicle into the shop and was informed of the "rotted out" pump flange was leaking. I paid almost $700 to have it fixed and complained to the dealer. 12 months later the GM/delphi pump failed and I had to pay to have it replaced again!

I own a 2002 Chevrolet Trailblazer lt. For the last two weeks there is a very strong odor of gasoline. Apparently it is leaking from the top of the tank. I understand that GM is paying for repairs of this problem on 2002 Trailblazer ext's under a special coverage warranty. If my vehicle has the same problem the ext, why isn't GM applying that coverage to the lt?

During routine driving I noticed a odor of gas from inside my vehicle. Upon inspection I discovered gas leaking from above the gas tank and onto the ground. I brought my vehicle to the dealership and was informed that the fuel module had rotted and therefore was leaking gas onto the top of the gas tank. The gas would then collect on top of the gas tank and cause a strong odor of gas inside the vehicle. I had the fuel module replaced for a total cost of $810.52

About 1 month ago we started smelling gas fumes and than we started to notice gas was leaking from our tank onto the ground. When we brought it into the mechanic they told us we had a leak in the fuel tank. Our car is a 2002 Trailblazer ltz and it just hit 52,000 miles. It has been garage kept the entire time. When we contact the dealer we bought it from they said it was no longer under warrenty and there was not tsb's out. After some research I found the tsb that was put out for this defect. I have not recevied a recall and am experiencing a difficult time getting this problem resloved.

I also had a noise from underneath vehicle getting louder over 3-4 days then smell of gas began and got very strong after a couple days. When it smelled bad we took it to a shop and the fuel sending unit and filter needed replaced. There was a small hole which was caused by corrosion that the mechanic said he had never seen this before. He said if I hadn't brought it when I did that the vehicle could have caught on fire.

  • Automatic transmission

Transmission does not shift smoothly and the vehicles seems to "skip" when driving, had checked and was told the transmission needs servicing. Also, several times the car has jumped from 2wd to 4WD on its own, while being driven. Thankfully only when going approximately 10 - 15 mph. Now the service 4WD light is on. Fuel filter needs replacing. Oxygen sensor needs replacing. This car is a 2002 with 71,000 miles.
