The fuel pump ground wire is loose. If you have a loose parking brake pedal or recently had it worked on, check the black and yellow wire that's on one of the screws that holds the Pk. brake assembly. It's hard to find, but it's up there. I guess it could be elsewhwere on the ground wire between the fuel pump and the grounding point by the Pk. brake.

Acts like it is out of fuel, I replaced the fuel filter and it ran good for a few miles then sputterd and died again and now wont start


Sound like your fuel pump went out. Turn the key to on postion and see if you can hear it turn on in the gas tank. It will be a whinning sound in the gas tank. If nothing it is you fuel pump need to be replaced.

Hey Mudkicker,

Who ever thought of putting an electric fuel pump inside a tank of gas........

Check your other gauges for accuracy. They do that when a ground is loose.

Check the wiring from the fuel tank along the longitudinal frame for frays and shorts. Plugs are secured.

Under the hood, passenger side, check the fuel pump relay. Switch it with one of the others to test it.

Bring the vehicle to an auto parts store. Ask them to break out he code reader. Check for diag codes

Comment me back
Mike.
