'90 Chevy Lumina 3.1 crank/no start when warm
When the engine reaches operating temperature and is intentionally turned off it will not start up again. On a cold start, the car will crank, start, and drive normally. The car will operate normally even after reaching operating temperature. The problem only occurs after turning the car off. I have good fuel pressure (approx 40 psi) cranking and running. I have even done an injector drop test to insure injectors are actually operating individually. I have good spark. I have attached the computer and I have RPM during cranking (crank sensor test). Has new MAP sensor. Any ideas???
