Well the tests I outlined earlier is the only thing I can tell you. Test fuel pressure, spark etc etc. Crank sensors are a big issue with Ford Modulars. They can test fine yet still not function properly. Usually though that's a no start issue. Since your car runs you need to test pressure and spark. Coils are problematic but cheap on ebay. Lastly, have you done a leakdown test or a compression test? Maybe the motor is bad.
