no fuel pressure

[BroncoKID34]

I have a 1990 Bronco w/a 5.8 351W(has been sitting for 4 years) I replaced the gas tank and the in-tank fuel pump but still no fuel pressure. ANY suggestions would be greatly appreciated.

high press. pump working/voltage...?

plugged fuel lines..?

"still no fuel pressure"

did you test with gauge..?

Injectors plugged..?

You probably have a bad fuel line that's sucking air.........Easiest way to figure it out is to lay under the vehicle, disconnect the fuel line from the fuel pump, and blw air thru it.....Been thru the same thing, and after $100 and several hours, it was just a cracked fuel hose.

Check the fuel filter and MAKE SURE you hear the pump pressurize (my new one is loud). Disconnect the fuel line at the coming from the tank to the filter, gas should come out on you.

Having had recent problems with this myself, find someone who has a pressure tester. There is a shrader valve on the fuel rail. I don't know what the pressure should be for a 351, but if you hook up a pressure tester and have fewer than say 25psi, or if it fluctuates, it could be your fuel pressure regulator. It's at the back of the fuel rail. Hope that helps.
