You could have a bad pressure regulator, it could be stuck/failed open and just pumping back into the tank via the return line...Mike.jlahood said:So I disconnected the fuel filter and turned the key on. Fuel pumped out through the filter. I hooked it back up and ran the pump a few times to prime it. I then pushed a small screwdriver in the schrader valve and there is no pressure at all.
Normal to recycle on for 2 sec when the ignition is recycled.jlahood said:So I bought a fuel pressure test gauge today. I did have fuel pressure at the schrader valve. But the gauge only went to 15 psi when I cycled on the pump. I guess that would suggest the fuel pump is too weak to pump sufficiently? I also noticed when I turn the key on the pump cycles on for about 2 seconds and when I turn the key off it cycles again for about two seconds. Is that normal? Where is the pressure regulator located at? I read something about it being under the intake plenum.
Thank you all for your help.
