Question type: Maintenance & Repair
My 1987 Ford f 150 died on me going down the
road. It would start with starting fluid. Found out it
was the fuel pump relay. Ran fine so I decided to
drive it to work Friday made it about 2 miles died
again. Got it home and found wires melted
together behind the selector switch. Pulled them
apart ran fine for about 10 minutes and now
nothing. Can someone please help me!!!

there is a reason the relay went out to lunch...the current draw from the fuel pump was too great...should have popped a fuse, but instead cooked the wires~ solution, measure the pump to see if it's drawing too much current, possibly replace that pump if too much current needed...replace the length of burnt wire and finally get a brand new fuel pump relay~ remember measure the amount of current...the fellows at NAPA auto parts store will be happy to do that...and possibly sell a replacement pump to you too~
Disconnect the wires going to the pump, remove the relay and check for a grounded circuit.
A relay is nothing more than a simple electro-magnet which directs power from point A to point B when the circuit is closed. If you fried the wires within the relay, or somewhere before or after, Best bet is you are experiencing a short within that circuit. However, the relay and accompanying wires should be protected by a fuse which does not appear to be blowing. You're pulling more amperage across a wire(s) than the wire is rated for, thus the melting.
Cont. The situation you describe is what one gets when one replace a 5 amp fuse with a 15 amp fuse. The fuse doesn't blow, the wire melts.
