problems with a grand prix
My buddy at work has a 00 Grand Prix. He is having problems with it. I know this is a B-ville forum but I thought it would make a good discussion and possibly get to the rootof his problem. Here goes:
Vitals: 2000 Grand Prix with 3800
When started the car runs fine, when temp reaches about 200* it starts missing and sometimes shuts off. No SES light If he can make it to the interstate and drive it it will cool down and drive fine.
Also:
On hot and humid day around 90*'* when the motor warms up and then he shuts the car off it won't start back until its completely cooled down. Sometimes it won't start back until a couple hours later No SES light.
He has not done anything to it tune-up wise either.
Thanks,
Tim

Okay I will tell him in the morning, I'll see him then.
I guess if it starts with cold water poured over it then it is a bad crank sensor right??
Thanks, Archon

Talk about the other 3800 powered GM cars, particularly for items not covered in other sections that may be unique to your year/model, and differ from a Bonneville.

In addition to the CPS that Dick mentioned, from the symptoms given, the car could have a large air void in the cooling system. Eliminate this possibility by ensuring that the level of coolant in the radiator when cold is all the way to the overflow port. Also, check the fuel pressure regulator vacuum line for gasoline to eliminate that as a cause of the no hot start.
