Just for precaution, check the "inertia switch" to be sure it's not tripped, and that it's working. Just unplug it, turn the key on, and you should see power through a tester connected to both prongs. Check each terminal to ground also just in case the pump failure blocks continuity to ground on the other end. Use a paperclip or some solid copper wire to bridge the two terminals on the connector to make sure that the inertia switch is operating correctly- it usually is, but it's worth checking before going through the motions to replace the pump.
It's extremely unlikely that there is a break in the wiring between the inertia switch and the fuel pump unless you've been cutting into wiring to find power for lighting/stereo mods. In order to check it at the pump, you'd have to remove the fuel tank, which is what you'll have to do in order to replace the fuel pump.
I wish both Ford and GM would take a clue from Japanese manufacturers and put a freaking access panel in the floor for fuel pump replacement.
