The car belongs to my dad. It's a very plain jane model, even has a column shift with bench seat. The day he bought the car (new) it was a rainy day. He drove it to the insurance company to update with them. When he returned to head home, the car nearly wouldn't start. He took it back to the dealer right away. The dealer did get to see it acting up. They took it into the shop. No codes were found and it began starting fine. Since then the car has started as you would expect unless it's raining or very damp. Occasionally on the wet days it cranks over but sounds like it's flooded. If he presses down on the gas about 1/3, it will start. It runs rough at first, but no smoke. Then all is fine, the car runs and acts as you would expect. The car hasn't left any codes, and the dealer doesn't know how to fix it. The car only has 16k on it, and is still in warranty. Has anyone here run across this with the 3800?

it sounds like and ignition problem. i've seen a few of these that get moisture in the igniton connector and they won't start.
what's the ambient temp when the problem occurs? does it have fuel pressure during the hard start? how often does this happen? call me if you need more info. mike

Check the fuel pressure regualtor
see if its leaking intermittently. will suck fuel into the vac line cause a long crank, and stumble when it starts. |

the reg is a common problem but i don't see the damp weather changing the problem.

I agree with you about the weather, but "1/3 throttle car will start" that is due to the introduction of more air allowing the mixture to fire.
I bet if when the car acts up again, if the fuel pressure regulator is immediatly checkd the line to the intake will be wet with fuel. |

Thanks for the replies. As this only happens occasionally on the wet days, it's been tough to dianose. At least now we have a couple more things to check. Again thanks much!

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
