I am confident we can resolve your problem together.Please remember I don't know your skill level. I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies to get to a satisfactory resoloution.I also try to give all of the information you may need expecting a positive rating. If there is any reason I cannot get a positive rating please let me know.
How have you determined that you have no pressure at engine? Do you have a fuel pressure gauge?
and you have 0 pressure?
Is it possible you crossed the pressure and return lines?
What was the original problem that you were trying to correct?
My immediate suspicion is that the regulator is stuck open causing fuel to return to tank.
can you try pinching the return line and see if pressure come up?
Yes top of engine in fuel rail
You can here the pump? Can you hook a pressure gauge up directly in the pressure line? Is it possible that you have a bad connection at pump? There is an updated fuel pump connector for these.
Can you hook your pressure gauge directly to pressure line as close to pump as possible?
Also I have had 1 of these that the wires were hooked wrong on the pump causing the pump to run backwards. it was an aftermarket unit. I dont remember the brand
What I am saying is the unit was wired wrong in the assembly causing the pumop to run backwards. If pup is running and no pressure there is something wrong with pump
It is absolutely a pump problem if it is running and no pressure
OK let me know what you find.
