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.

 

Post the specifics of the car.... year, model, engine, tranny and any major mods. Without that info, you reduce your chances of getting an accurate answer (or any answers at all). Us the "Signature " field and you will not have to type that info every time you post. We can guess you have some sort of 2000, but there are many people here have have embedded car info in their screen name that has nothing to do with their car.

When you say you have no fuel pressure on the gauge, what gauge are you looking at - a test gauge connected to the Schrader valve on the rail, or an electronic aftermarket in-car gauge?
