1 Answer


If you replaced the front fuel pump then the resistor and sending unit, part of the pump assembly, should be good. Check if a voltage is being supplied to the gauge when the front tank is selected and ignition switch turned on. If no voltage, backtrack wiring to see if their is a ground issue.
