Default need help fuel problem
last night the car had over heated then cooled down it was the electric water pump. Then after having it on for a bit it turned off and i have no fuel psi at all on the gauge the pump is new i can hear it still working. i opened it to check and it was good. what do you think it can be fuel filter, regulator is a holley. or the fuel thing.

So you have a gauge hooked up the schrader valve on the rail and you are getting zero fuel pressure? If so and you are sure that the pump is actually turning on, and you still have no pressure, then most likely your pump is bad or your regulator is bad. Usually a dirty fuel filter will give you low psi, not zero. But if you haven't changed it in a while, you might as well do it to see if it helps, it's only like 12 bucks. Pull the vacuum line off of the regulator. If you see or smell fuel coming out of it, then the diaphragm of the regulator is bad and you need a new one.
