Chrysler Repair: 95 Caravan electrical, injector pulse, correct numbers

Question
I have a 95 Caravan that just up and died. So far, I have determined that the PCM is not grounding the fuel nor ASD relays and allowing the fuel pump to work. However, if I ground the relays manually. the pump will run non stop.  I am also not getting any voltage at the ASD and fuel relays during the initial 1 second of cranking it takes for the PCM to determine whether correct conditions are met to allow engine start. We are getting spark at the plugs which leads me to believe the distributor, crank and cam sensors seem to work and we have swapped the PCM for another out of a wrecked Caravan although it's identical but not the exact same model number of PCM. Any ideas? Thanks.

Hi Lorne,
Before I forget, when/if you write back tell me which engine you have in your van.
I wonder if you asked the old or new PCM for whether it had stored any fault codes in its memory? If not, use the ignition switch: on-off-on-off-on within a time period of 5 seconds or less. The check engine light will stay on but then begin to flash, pause, flash, pause, etc. Count the number of flashes before each pause, write it down, then repeat to verify you have the correct numbers. Then group them in pairs as they came, to form two digit numbers. The last number will be 55, two 5 flash groups being always the last to report out which is the code for "end of readout".
You can get a decoder at: www.allpar.com/fix/codes.html
Then let me know what the numbers were and how to respond to the faults.
I am a bit unclear but did you mean that you can get spark by manually grounding the ASD only? O.K., but that still doesn't prove both the cam and the crank sensors are alright. One of them does the spark, the other does the injector pulse synchronization so just getting spark doesn't mean you are also getting injection pulsation. That is why you need to check the codes.
If you aren't getting any voltage output at the ASD in the first second of cranking, but you can ground the coil of the ASD and get it to close and power up the spark and fuel, then it would seem that the issue is with the PCM or the wire to the PCM from the ASD. If you got voltage out of the ASD for a second or so, then I would think of the sensor(s) as the problem. So again please clarify what is going on relative to power for the spark and fuel pump without any jumper intervention. And which engine?
