no spark 94 dodge caravan 3.0

no spark at plugs or distributer of daughters '94 caravan. There is intermittant fire at coil when ignition turned on, vehicle turns over w/o problem, Already checked the usual items: coil replaced; computer checked, distributer components replaced, fusible links not found, all ignition fuses and relays checked and replaced but no problem found. ignition switched replaced. Any ideas? Need help thanks this vehicle has no crank shaft position sensor or knock sensor.

I'd think it be the ignition module. AutoZone says $109. Module doesn't fire, coils don't either, neither will plugs. Let me know!!

Is the ASD relay clicking when turning vehicle over? It is on the left front fender. Try tapping it and start. Or unplug it and check terminals to make sure you have proper contact.
