Coolant Temperature Sensor?

[joshnumber21]

OK, I know I posted SOMETHING about this in my last thread, but it turns out to be unrelated to the sensors I replaced (Crank and Cam sensors)

It WONT fire up on the first cranking sequence ever when cold, or after sitting 4 or more hours, and sometimes not on the 2nd, but even when it does on the 2nd it fires up too quickly, almost feels like a jack-rabbit start, I've had a few people hint at the Coolant Temp. Sensor, anyone second that notion, or if not, what are your guesses?

Check your fuel pressure when cold and when you try to first start. you could have a leak and it takes time to build up pressure.

Tried it. 40 psi throughout. no visible leaks or smells either.

The leak could be internal, back to tank. Do you have fuel pressure before you crank the engine ? While cranking the engine ?

[joshnumber21]

yeah, I checked the pressure before and during cranking, and it remains at 40 psi.

Check to see if you have spark on the first crank.
