Ford Repair Questions? Ask a Mechanic for Answers ASAP
There are a few posibilites here that you can check before you take in it. I have included the diagrams for the interior and the under hood fuse panels with the fuse marked and the fuel pump relay marked. Thats about all you can check unless you have testing equiptment. If you do, let me know and i can send you the wiring diagram.

Here is another diagram of the wiring to the inertia switch, test to see that there is power to it from the relay. If it doesnt, it's probably the relay, if it does, junmper the wires and the pump should come on if the switch is bad.
Best of luck and let me know how it goes.
