Hi,
Power is sent to the fuel pump via the open relay, under-hood fuse box. Switch it with a different relay having the same part number to see if that changes anything.
Next, if you go to the fuel pump connector, locate the blue wire with a black tracer. Probe it for power while a helper turns the key from off to the run position. Is there power? If there is, we need to check for a ground path.
Locate the white wire with a black tracer and check it for continuity to ground.
