Get a code reader like the Actron CP9015 Code Scanner, 20 dollars and will flash codes. if it will not diagnose itself, the ecm must be replaced. this fixed my dads truck with the same problem

    Locate the relay by popping the hood and look on the drivers side fender near the firewall for a black plastic rectangular shaped box. This houses a few different relays that will be labeled. The fuel pump relay should be the green connector with a black relay. Disconnect the relay being careful not to break the locking tabs. Get yourself a short piece of wire to use as a jumper. Strip the ends and jump between the green wire with the yellow stripe, and the red wire. turn the key to the run position and listen for the pump. If it comes on great! Go buy a new relay, and you should be back in business. If the pump does not come on, leave the key in the run posistion, and check for power at the fuel pump, if power is there, then have a nice day changing your fuel pump ; ) If there is no power, I can't really say where to start except start checking grounds. Hope this will help someone, and good luck!

1991 ford f150 fuel problem

Is it possible the fuel hoses are not hooked up right ? If you only changed the rear pump and the lines are correct, its possible the new pump damaged the check valve in the front pump. The valve could have been about to fail before replacing the rear pump.
You may be able to block the line going into the front tank and run the truck from just the rear tank.

Where is fuel pump on 1991 f-150?

Your fuel pump should be in-tank for a 91 F150. To access it, you will likely need to drop the tank.

You should verify, however, that there are no ignition problems before considering the fuel pump and always remember to replace the fuel filter with the pump if it does turn out to be the pump.

93 f150 changed tank and pump rear truck will not start

Make sure all the wires to the fuel pump are hooked up. listen to see if you hear the pump turn on when you turn the key on. If it has two tank does it start on the other one. make sure you have it switched to the right tank. Check your fuel pump fuse and relay under the hood.

How to change a fuel pump on a 1991 F250 351

The fuel pump is in the fuel tank. One in each tank. You'll end up having to drop the tank down to replace pump. A little time consuming, but not a big deal. I had a pump go out in my F150, but not until I just topped off tank. That was a pain.
