fords have a fuel bump switch which will shut the fuel system off on impact.
they have been known to bump open on ruff roads or no reason at all.

Did it work one day and just not start the next?
Are you on the road and it died on you?
Have you done any mechanical/electrical work recently, like last day or two?

With either a test light or voltmeter you can check at the tank to see if you're getting voltage to the pump. If you are then it's likely the pump died.
If you aren't then that switch above could be the problem or a simple fuse (check first) or the fuel pump relay. A way to check the relay is to jump the connections coming to it for power to the line going to the pump.
That switch above might also be called a roll over switch or inertia switch.

Check out some youtube vids for how to on jumping the fuel pump relay if you feel comfortable doing it after finding it.

Remove the gas cap and listen. Have someone turn the IGN to ON. The pump should run for 2 or 3 seconds. Its not very loud so listen carefully.

Check the switch that iamcaper mentioned. Its mounted almost directly above the gas pedal.

In the fuse panel above the radiator. It should be a fuse #21, a 20 amp fuse. If you look at the photo on my web site, it will be the right side 20 amp fuse just below the yellow alligator clips.

If you're comfortable with electrical, I'd remove the fuel pump relay and jumper across the connectors to see if the pump runs.. You can also swap relays to see if its a bad relay.

I changed the fuel pump on my 1999 F53 last spring. Here is an article with a lot of photos:

NOTE - Theres a lot of other F53 stuff on my site that you may also be interested in.
