Ford: Ford Problems, ford f150 4x4, ford problems


Question
I have a 1991 Ford f150 4x4 with 302 efi. . . problem is it wont start and I have no ground to the fuel pump or the ignition checked all grounds from battery to fram to body and all are ok. . .I can the ground fuel pump at relay and fuel pump will work , but cant find the ground for both...?

Answer
Don't know where the ground is on that one.  From what it sounds like the fuel pump is grounding and the relay isn't.  The relay has to be grounded before it will close and allow current to flow to the fuel pump.  Try running another ground for the relay and see how that works.  The fuel pump should have its own ground through the harness that plugs into it.
