Pontiac Repair - Sunfire stalls while driving

Expert: Todd Puccio - 10/25/2009

Question
My car is a 2002 Pontiac Sunfire, 4 dr, 4 cyl, 2.4 L ecotech engine. It stalled the other day after starting it, it ran for about 5 seconds then stalled. It took about 6 tries to get it restarted and that was after pressing on the gas alot. After it did start it smelled strongly of gas. Took it to GM service, they replaced spark plugs, fuel filter, air filter, and did transmission service, also ran diagnostic and checked fuel pump and said they could not find anything else wrong. Second day after bringing home stalled while driving while turning a corner. Took about 5 tries to get it restarted. After stopping and shutting off engine then restarted fine. Seems to have no pattern to stalling, happens when stopped or driving. The battery is less than a year old, radio and etc still work when it stalls. When trying to restart it does try to turn over just is not successful.

Answer
Hi Amanda:

This is a bit of an odd one. For the most part this is a pretty solid engine package in that car and we do not see amny stalling issues at all with them. before it quit running aor once yougot it back running was there an service engine soon lamp that has come on? that would be a place to start looking.. when this quit running each time was there about the same amount of gas in the tank? I'm thinking possably a fuel pump issue here. was this the first time the filter was replaced? If so it may bave been plugged solid and stredd the fuel pump out to the point where it' cutting out from time to time.. Whan need to be doe is wheo ever is fixing it has to drive it and hope it quits on them so they can find out what is missing here as to why it quits running.. second though would be an ignition system issue like a ignition module or crank shaft peosition sensor. But agin with out it quiting on someone it's just a guess as to what the issue is. Good luck :)
