my fule pump works and all wiring works going to the pump except at the last connection. i ran a wire to the battery to see if fuel pump works and it does. I also tested the voltage on the last connection and reads good. but when i connect, there is no voltage and dont work. any suggestions?

Check for proper grounding of the fuel pump circuit. Test wire for internal breakages by tugging on the wire and testing for battery voltage.

Uunder such situation, either the connector is bad or there is a breakage in the wire between connector to fuel pump.

Backprobe the connector on both ends to test for continuity.
Test wire continuity between connector to fuel pump.
