Use a multi-meter and see if the pole piece/reluctor that connects to the module (2 wire connector) produces an A/C milivolt signal while cranking...this is the primary device that signals the module to fire the coil as its turning in time with cylinder strokes

Ok... try this. Get a multi meter, turn the key in the on position. In the dc volt readings, put black end of wire to engine ground and red to small wires (primary side) on the coil. Do you read 12, maybe a little higher, up to 14 volts on the meter? If yes, then you are getting juice from battery through the ignition switch that should be supplying spark. If not reading any voltage with key on, you may be looking at a bad ignition switch. There are several connections made in that unit and it's not unusual to go bad once in a while. Let me know if that doesn't work. Thanks. Please rate this info.

Why my 94 Astro van will not fire


this generation of gm vehicles is easy to troubleshoot. the engine needs 3 things to run: compression, fuel, and spark. since you mention fire, i assume you have no spark.

disconnect any random spark plug wire and connect the end to a hei spark tester. crank engine and observe for spark. if you have no spark, disconnect the center terminal of the distributor cap and use the hei tester in the same manner. spark means cap and rotor bad or bad plug wireset. no spark means make more checks.

check for battery voltage and good ground on distributor. check for open or shorted ignition module or ignition coil windings. if power and ground is present and ignition coil tests ok, check for ignition pulses at coil primary. if you have no ignition pulses feeding the coil, change the distributor.

with that generation of vehicle, the ignition system will operate without help from the computer. don't even troubleshoot the guts of the distributor, if you change the cap, rotor, and anything else, it will be the same price as a remanufactured distributor, and might not fix the problem. if you troubleshoot a low volrage related issue (no pulses, shorted or open circuit, unstable timing, etc), change the whole thing.

I guess you could have the ignition analyzed on an oscilloscope. Maybe a tech could see something then.
I always heard the only gap was the spark plug gap-the rotor has no gap-are you sure you got the correct rotor? And does it touch the top distributor cap coil wire tower?

Let us know. It is a mystery worthy of a solution.

I had the same problem with my 85 cj7 this week, I relpaced the ignition control module, plugs, wires, cap, rotor and the the coil; still had no fire to plugs. the problem turned out to be my distributor, replaced it today and she fired right up. Most likely it was the pick up module in the distributor that went bad.
