this truck is equipped with a tfi ignition module which is a common problem,but inside the distributor is a hall-effect sensor that provides the trigger signal and basic timing info to the ign. module and the pcm.they are difficult to test separately.consider replacing both, or take a chance and replace ignition moduule first and try it First, make sure that the coil has key-on power, and make sure power and grounds are ok fords are real funny aboutr that

Yes, many things can contribute to an ignition failure. A distributor stator, a module, key power from the ign switch, power to the coil, a bad coil, broken wires, worn distributor bushings causing the vanes to crash into the stator - there's a method to diagnosing a concern. You could throw money at it and get lucky though.
