Let me clarify my earlier reply. Check for 12 volts at the ignition coil for the first second after turning on the ignition switch. If you turn the switch on, then run to the front of the vehicle, there will not be voltage on the coil. It is only there for one second, so you'll need a helper to turn the switch or you'll need to prop the meter or test light so you can see it from inside the vehicle. If you never see voltage there, I would first suspect my probe wasn't making good contact with the terminal. If there still isn't voltage, suspect the ASD relay, which you already switched, or the wiring to the coil. The Engine Computer is next, but I'd be surprised if he was the problem.
If the voltage is there for the first second, it must come back during cranking. If it doesn't, that's the time to head to the crankshaft position sensor. Since that didn't help, the next thing to try is the camshaft position sensor. According to Chrysler, his purpose is for synchronizing fuel injectors, but on Chrysler vehicles, this sensor will result in no spark AND no fuel if it is defective.
The cam sensor is in the distributor. You can test it with an old pointer-type voltmeter. The signal wire voltage should pulse between 0 and 5 volts during cranking. If it doesn't, replace that sucker.
