My fuel pump does not engage when the key is turned to the on position. I replaced the pump, filter and the fuel pump relay and the pump still will not engage. I tried tracing the wires as best as I could, and found no fault damage. Any ideas?

Check all fuses and fused links. Check fuel cutoff switch

Hi Yes,
unplug plug for pump at the pump have someone operate key for you.

Check for power when key is on one wire will be powered all the time the key is on this will be low voltage, one will be ground. But one will be powered for 3-5 seconds only if you have a wire at the pump that is powered 3-5 secs and then goes off. This means everything from the key to the pump is working. If you don, t then go to the relay box and check power at the relay center. Power goes mfrom ignition to relay to pump
