[DML] Re: Warm Start Issue (David McKeen)



Because the pump isn't spinning for 1.5 seconds. The pump spins for a
fraction of a second when the car is first energized, but until the
engine is running that's it. The pump does not spin as the starter
motor is turning the engine.

If you're so obsessed with this vapor lock theory, bleed off all your
resting pressure (manually depress the air sensor plate), jump the RPM
relay (forcing the pump to spin), then try to start the engine.
Assuming rest pressure is the only problem with your car, it will fire
right up.

Fuel vapors are no problem for an 80 PSI pump.
