Try resetting the Inertia Fuel Shutoff switch.
Edit:
If you can not hear the pumps run at all you do not need the fuel pressure gauge.
The pumps need to run for one second when you turn on the key with the engine not running. We need them to do this before we look at the fuel or the Ignition systems.

the switch your refering to is the one on the fire wall under the drivers side, i was under the assumption that you only did that if the truck was in a wreck,its worth a try not sure how the reset works though .

Just went through this with my '91 F350 and it turned out to be the EEC. When it goes it can also take out the ignition module which sounds like it is not your case. The EEC for '91 is unique to '91 only whereas other years EEC covers several years models. Hard to track down the '91 EEC because of numerous part number changes.
