Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Well, I bought this car used last year and for about a month it was running wonderfully. All of a sudden, the Check Engine light comes on and I hook up to the OBD to pull some codes. Not surprising it's one of the O2 sensors. I replace it and the light goes away. About 2 weeks pass and then one morning, I can't get the car to turn on. I tried for about 2 minutes until it finally turned on. I figure it may be an electrical problem. I check the ground cables and have the battery tested. Every checks out ok. I move on to replace the air filter (although, the one in there was fairly new.) I installed a new fuel filter, fuel pressure regulator, spark plugs, wireset. It's still a pain in the ass to turn on! No codes come up, fuel pressure is normal. I have no idea what to do! Any ideas?
