Now I have been told a variety of things.. with the problem I am having. It is a 1992 Park Ave.. I can drive it as long as I would like but If I shut it off it will not start again until basically cooled all the way off! Now I was told IGN Module, replaced it did not fix it.. Cam Sensor replaced it, also did not help it! I heard that the crank sensor is also a very good possibility, and just today I talked to another mechanic I know and he said the "coolant temp sensor" almost positive that is what it is.. He said if it was the crank sensor car would not start.. Does anyone know, or have any input on this..? Thanks.. its a 3800 non-supercharged (josh)
