Look for a shorted wire or make sure your inertia switch isn't engaged. I think it is on right kick panel just forward of door

The switch is not engadged. And I cant seem to find any shorted wires. The main power to pump will have power to it only when harness is undone from fuel pump. When I connect the harness to pump and check the wires for power it turns to a full ground with switch on or off

Im thinkin I shorted the pump out somehow. I have a power probe that if I put power to pump through the main wire it will kick on so thats what got me confused
