Why are my brakelights, reverse lights, tail lights and blinkers not working?
I recently changed my fuel pump out and I removed the bed of the truck to gain access I put it back on but now none of my lights work when the headlight switch is turned on. when it's off my brake lights and turn signals work fine
If these are all rear lights - check the wiring to the lights - common wires along the circuit. May have been disturbed with the recent fuel pump work.
