You're right about the Automatic Shutdown (ASD) relay. You wouldn't have spark if it wasn't turning on. That means the distributor is working. Since it won't run on starting fluid, there must either be a problem with the timing belt, (unlikely that both are wrong so it should try to run on three cylinders), the spark plugs are fouled with raw fuel, or, (and I'll never admit I did this once), you had the rotor out of the distributor and forgot to put it back in! It wouldn't hurt to verify there is spark at the plug wires if you only checked from the coil wire. The GM HEI system had a lot of trouble with "punch through". That's where when a plug wire was removed and held so far away from ground, the spark couldn't jump the gap, but the voltage was so high, the spark insisted on getting to ground somehow, and that was through the rotor. Once that happened, it left a carbon track behind and from then on, all the spark current went through that short. The cure was to replace the rotor. I never heard of that happening to a Chrysler rotor, but double-check just the same.
