Hi Chris'
It sounds like your engine is using Fords EEC IV. The control units are pretty bulletproof.
They use two relays to power the system, these are bigger than your standard "box" relay.One runs the pump and the other the ignition. If either doesn't work the engine won't start. Take the cover off the fuel relay and close it with your finger (with key on). If your pump runs your relays faulty. Do the same with the EEC relay (with key on). Your EEC LIGHT or CHECK ENGINE LIGHT should illuminate. If it does then its your relay.
If it is the relay clean the contacts and carry a spare in the car.
Eec iv is the Ford Electronic Engine Control iv (four) system. Google eec iv and learn heaps, like how to read all your engine info with nothing more than a test light and a short piece of wire.
