1994 Chrysler Voyager 3.3 ES Non Starter

1) No Spark
2) No Power to fuel pump, Relay Ok , pump Ok
3) Crank sensor Ok
4) No Diagnostic Codes at all being displayed using the cycle Ignition key.
5) Getting power into the (PCM) located under the battery tray. but NO power out to the ASD relay

So is the PCM damaged ? we presume so.

Have been searching for 6 weeks now for the correct part number. Every search I have done with the part number taken from the PCM its like it does not exist. !!

Next problem I found when searching for the part using the VIN number has said its not a valid VIN or does not exist !

SO

If I find a PCM with a different part number but from a car with the same specs is there a chance it will work ?
Any ideas guys??
