Based on the wiring diagram, the fuel pump gets its power from fuse #23 20A in battery junction box, left rear of engine compartment through the fuel pump relay which gets its trigger from the PCM relay (powered by fuse #7 30A). From the fuel pump relay power travels to splice S111. S211 splits to 2 wires:
1. #16 dark green/yellow piggybacks to the PCM
2. #26 dark green/yellow to inertia fuel safety cutoff switch. From there it goes to fuel pump and to ground G205. There is a second trigger from the PCM through #12 yellow/white wire to splice S222 to the fuel sensor and grounds to G204.
Initial diagnostic always asks that we check the IFS switch. Looking back at the diagram, I believe your fuel pump relay may be at fault. There should a few relays under the hood that are similar to the fuel pump relay. Switch them around and see if that works.
