Re: STARTING PROBLEMS



Until the engine is actually up & running, you depend on gas stored in
the accumulator (DeLorean don't energize the pump until a certain RPM
-- anybody know what it is BTW?). But the accumulator diaphragm does
not live forever, failing to hold fuel or pressurize the system. When
cold, your cold start valve shoots raw gas into the intake, giving the
engine enough fuel to bypass such a difficulty. You can swap its
electrical plug with the control pressure regulator's to do the same
hot, but do so judiciously -- the engine will flood within seconds.
You can also jump the fuel pump relay, forcing the pump to spin as
soon as the car is energized.

Make sure you don't have a Brand X fuel pump without a check valve
like me, in which case the best accumulator in the world won't do any
good...
