Check the fuse box. The main fuse to the starter might be blown.

Is the fuel pump inside the fuel tank? If, so, you could try disconnecting the wire harness at the tank, and hot-wiring the fuel pump directly to a 12 volt source, in the correct polarity of course! If the pump runs, your problem may be a fuel pump relay, or a wire problem or connector problem. If the pump does NOT run, post that info. There may be a way around the problem!

Yes and a relay. Go to ford.com/ownersmanual. The manual will tell what the fuses run and the relays.

Since it is so old, Start with a compression test. 90lbs is about minimal. The cylinders should be with in 10% of each other. If your there or lower, Time to retire or rebuild this engine. This part here will save you time, trouble and money into an engine that won't be any better when your done.
