I am mad as hell and I am not gonna take it anymore. I am fed up!!! The car doesnot have any faults at all except for when I shut it off and try to restart. It has to sit for a while and then it will start up. I was thinking maybe it's the coil or module but the car pulls strong and nothing for me to consider that as a possibility. I swap the MAF, fuel pump relay, and ECM and no help there. Could it possibly be the CAM sensor? I was told there is no such thing as a dying cam sensor. They either work or they dont. Can someone here chime in and help me out.
What the hell in the world is causing my hot start problem???

Where you say you have tried swapping the ecm, maf , and other, get it hot and shut it off where it doesnt start and pour ice water over the coil and module and see if it starts, I have had stuff run fine as long as its under a certain temp,

i was just reading up on thread somewhere about coil heating up causing that, meaning it runs fine untill you shut it off then phifft, its either coil/mod or starter solenoid and if you go to start and its not doing the roh roh roh then its got to be heatsoak in ignition?

Something is getting heat soaked, which increases resistance. I'd focus on the coil pack and module.

It's usually the Module they get heat soaked and don't start.Try cooling it off with water and see if it starts.
aprroximately 2 months now, no work at all, the enging turns, the starter has about 3000 miles on it.
I have heard of this before and will turn it down tonight.
Coil pack and module are original from 87. Car now has 62K and the starter was changed with an original GM unit when the car had approximately 59K
So this problem started happening right after you had the starter replaced?
Why did you have to replace the starter?
I would suspect the starter or wiring.
Since all we can do is guess at what is causing the no start condition.
It will be more useful to do some testing / troubleshooting. :smile:

Crank sensor …..
Get the car warm, and make sure it will not restart.
Check for spark. If no spark, get a can of Brake Cleaner and spray the sensor.
This stuff not only cools the part down “quick”, it cleans as well
.If it starts, you found the culprit.
Work through the process of elimination, and spray (not all at one time) things like:
• Oil pressure sender
• Crank sensor
• Cam sensor
• Coil
• Ignition module
Also make sure the fuel pump runs (I know you already replaced the relay) because hot "thin" oil requires higher cranking RPM to bypass the oil pressure sender.
If all fails, join the Houston Buick Club (Shameless plug
) and someone will help you get this done.Do you have access to a Caspers Coil Pack/Module Tester?...anyone near you have one?...that would be the best way to tell is it's the coil pack and/or module...get the car hot...shut it off...then use the tester...would be pretty obvious if the problem is the coil pack/module...
