Thought I'd post this here as I think the Bonneville has this engine, too. I have a 2000 Grand Prix GT w/3800 V6. Has about 89,000 miles. It seems to always start when it is cold. After it warms up completely, if you turn it off (to go into a store, etc.), and try to start it again, it sometimes will not start (happened about 3 times in the last month). It turns over, but won't start (sounds like it is flooded). It will sometimes eventually start after numerous tries, but will always start when the engine cools completely. We took it into a decent local shop, but they told me it hasn't thrown any codes. They said it could be the crankshaft sensor, ignition module, or fuel pump. They don't want to just start replacing parts as each repair can be costly with the fuel pump being the most expensive. We were hoping that it would start failing more often, especially when they had it (it always started for them) as they can't really do much as long as it always starts for them. We thought the car problems were consistent (always starts when when cold, sometimes won't start when warm, but will eventually start when engine gets cold), but it threw us a curve the other day when the engine stalled while my wife was turning into our development. Luckily, she was able to coast it a half mile to our driveway. Again, after it cooled, it started. I have heard that a bad battery or one that will soon fail (or one that is defective) can possibly cause this (the battery in the car is 4 years old), so I might take it to a shop and have them check it and maybe replace it anyway as this would be the cheapest fix that I can do myself. Has anyone had this problem w/the 3800 V6? Any advice? I'm hoping that if the battery doesn't do it, the car will start failing so the shop can fix the problem.

Replying to: neustkg (Feb 02, 2008 10:58 am)  Initially it would start after a couple of tries but then once I had to have it towed as it wouldnt start for over an hour. The mechanics are stumped - no codes so far. The fuel pump was extra loud, and after a lot of attempts at diagnosing (1 week), a GM 'specialist' said it was the fuel pump. Got that replaced and guess what - it wasnt. I have been reading up on this problem for the last two weeks and it could be so many things - right from Cam, crank sensors, the MAF sensor, clogged fuel filter, etc. Compression tests were done - no problems. The sensors as i said did not throw any codes. I've asked him to put some injector cleaner and see if that helps. I tested my battery - it was fine. I tried to jump start it once but that didn't help. (Also, all the lights and the radio come on, battery seems normal) Again, the problem is that the mechanics cant seem to reproduce the problem. They managed to do it once and detected low fuel pressure (and i replaced the pump, but the problem still occurs). Something is not letting fuel reach the engine. It seems like a minor problem, but diagnosing it is killing me.  I'll make sure to update this post - hopefully it might be of some help to you.
