    Key turned on, not cranking. I also have an error code of 54 on the diagnostic trouble code. (42 and 43 as well.)

Check for 12 volts power at the fuel pump harness. If no power is going to the pump, check the fuel pump relay. Also, check the fuel pump inertia switch. Ford usually has it on either inside left or right rear trunk fenders.

Fuel pump stays on after engine is turned off The pump continues to run for several hours discharging the battery


Unplug the fuse going to the fuel pump. If this stop the fuel pump from running. If it does, then go to the fuel pump relay after plugging the fuse back in and unplug it and see if the pump stops running. If it does the relay is stuck in close position and will need replaced. You can uplug the fuse and replug the fuse to the fuel pump until you get it solved. It usually is a yellow 25 amp fuse that is under the dash.

There is not fuse for pump but a relay in the relay block. I do suggest jumping to see if pump turns on. Test voltage from ECM if needed. If voltage is to pump, then pump is shot. If not voltage, relay may be bad

1992 1500 will not start


even though the relay clicked dosn't mean that it's good it could be weak and therefore the gate inside the relay doesn't make a contact to allow the voltage to the pump. i would switch out the relay. quick way to find out for sure is to switch the a/c clutch relay with the fuel pump relay. it should start if it doesn't then you have a loose wire to the pump or a broken wire aor a bad ground. check these out.. please rate this..thanks
