Fuel pump fuse blown or the fuel pump is defective even if you hear it running. Fuel filter can also be clogged.
Check the ignition module & pickup. You may find the problem there.
I know on my 1992 F150 it is under the hood behind the washer fluid reservoir in the black plastic power supply box with large fuses,relays and diodes.If you have duel tanks then their is one relay for each fuel pump.Hope this helps.

Do you have fuel pressure at the rail? Has the timing been changed significantly?
you should have six big relays in your fuse panel and between them are 5 small ones.its the small one in the center
check the relays above the brake booster check the relays above the brake booster relay above brake booster

no you have to get the fuel started from the tank
Replace the fuel filter.
check all fuses and relays first, if it is not this it will be the fuel sending unit which should be in the gas tank
Normally the fuel pump relay is separate from the AC. You can pull and switch positions of identical relays, depending on what you are trying to accomplish. If the fuel pump relay is working, and the rest of that circuit is okay, you will hear the fuel pump come on with a little whirring noise when the key is turned on.
check the fuel pump driver moduel located behind the spare tire
