Re: Help with fuel pumps!?!
See my earlier post, I had problem with my fuel pumps not shutting down after turning the ignition off. Found out the problem was the fuel pump relay that is mounted on top of the drivers side inner fender. I had trouble pulling away from stop signs and lights. But sure is good now, and I believe the relay was causing a resistance to the fuel pumps and a low voltage would not bring up enough pressure for the injectors.
However, you didn't mention cleaning out or replacing your fuel filters. On my 88 F-150 there is the stainless steel one mounted on the frame, but further back there is another fuel sediment bowl which your line runs through, so check them out. You even could have got a new faulty fuel pump relay too.
