My youngest brother came to me the other day and wanted me to look at his 1987 Pontiac Bonneville.

He is a good kid. Just made it through his freshman year in college and doesnt have a lot of money to spend at the dealership to get this thing working right.

(Front wheel drive, small-midsized, four door auto with a V6)

It has been a while since I have done anything to a car like this.

I know that the problem he is having is common for this kind of car but I cant remember where the information I have on the repair needed is.

(I don't keep things like this around, I like RWD and carburetors)

His car is in good mechanical shape with exception to the following issue:

The car will start only after it has had a couple of hours to get cold.

The car starts up fine and goes wherever he wants to go, but when the ignition is shut off, he is stranded until the car is cold enough to start again.

I remember reading a lot of information on this kind of problem in these early computer cars.

I cant remember the solution.

Is there anyone out there that does?

Doc here,

First determine if it is fuel or fire deprivation..If the fuel is good,

Have the module tested, and tested several times. It may be going thermal after shut down when heat soak raises the under hood temps..

Check the MAF and MAT sensors..also the Temp SENSOR (not sensor) to be hooked up and operable.
