1994 Ford Ranger cranks but won’t start

I strongly suspect its the ignition control module.This one is used on many years of Ford products and is notorious for failing, ESPECIALLY on engines with rear-mounted distributors. (Not one of Ford's "BETTER IDEAS".) Do this: IMMEDIATELY after the engine dies, check for the presence of spark at any spark plug, Using a timing light is the easiest way. Odds are there won't be any. NEXT, apply ICE to the distributor and module for atv lkeast a minute where the module is mounted. Using cloth is better than a plastic bag for obvious reasons. This should cool the module enough for the engine to restart if that's the problem. To double check this you can use a hair dryer on the module to MAKE the engine die. If YOU replace the module yourself, make sure that you don't forget the ELECTRICALLY CONDUCTIVE GREASE . That needs to be between the module and the distributor for the ignition system to work reliably.
