Im.dont have anythi ng to check that with its been an on gojng issue but it has gotten better with everything I have replaced that could have anything to do with it so far

This always happens after I have started it a few time after I have run around in an out of places with in a half hour if it sets over night it starts fine
Expert:  Amedee replied 11 months ago.

I would check the fuel pressure sir. You could be leaking fuel into the engine through one of the injectors or the fuel pressure regulator. This will cause the fuel pressure to leak down with the engine off.

Another possible cause would be a faulty cold start injector or a bad engine coolant temp sensor.
