93 Bronco 5.8 motor engine turns over but will not start. Fuel pump is coming on. I have replaced the starter solenoid, the starter, the cap, the rotor, still no fire up. Before replacing the above- the engine would run but it would barely idle then it would rev up &down-

The idle problem sounds like a bad idle air control valve or a vacuum leak. However, now it won't start. Have you checked to make sure there is spark to the engine? Have you checked to make sure fuel pressure is within spec?
