I have a '99 Grand Prix GTP (3.8L V6 Supercharged), and I have been having problems with it failing to start. It had been running well without issues, then it wouldn't start. I had it towed to a service center, and it fired right up. They couldn't find the cause. Same thing happened again, and again started right up after the tow. The third time it happened, the engine started but then ran rough and stalled, and now won't restart at all. Had it towed to a service center again, and they say it needs a new fuel pump, but I'm not convinced that is the problem? Anyone had similar experiences?
Thank you!
