Re: Looking for the Power Control Module, PCM, on 1996...
The PCM will be to the right side of the steering column where it comes through the firewall as you look under the hood. there will be 2 wire looms, one is the back side of the fuse box and the other is the PCM.

Powertrain Control Module/EEPROM Replacement/Programming
Powertrain Control Module (PCM)
Notice: In order to prevent internal damage to the PCM, the ignition must be OFF when disconnecting or reconnecting the PCM connector.
Service of the PCM should normally consist of either replacement of the PCM, EEPROM re-programming or a KS module change.
If the diagnostic procedures call for the PCM to be replaced, the PCM should be checked first to see if it is the correct part. If it is, remove the KS module from the faulty PCM and install it in the new service PCM. The service PCM will not contain a KS module. DTC P0601 indicates the EEPROM programming has malfunctioned. When DTC P0601 is obtained, re-program the EEPROM. If a DTC P0325 is set, check the KS module for proper installation. If it is installed correctly and DTC P0325 is still displayed, replace the KS module.
The ignition should be OFF for at least 10 seconds before disconnecting power to the PCM so the IAC valve has time to move to the engine OFF position.
- Faulty Powertrain Control Module (PCM)
- Powertrain Control Module (PCM) harness is open or shorted
- Powertrain Control Module (PCM) cicuit poor electricl connection
- Low battery voltage
P 1794 is Powertrain Control Module Battery Direct Power Circuit..I would be looking for a short in the wiring harness. I think the PCM power is shorting out to ground. Have you done any electrical work ( added an amp or stereo).
Detach the wiring harness connector(s) from the ICM.
Remove the mounting bolts, then remove the ICM.
Position the ICM onto the inner fender apron and install the mounting bolts. Tighten the bolts to 22–31 inch lbs (2.5–3.5 Nm).
Attach the wiring harness connector(s) to the ICM.
Connect the negative battery cable.

tragik nc: In looking this car up in both the 4 and 6 cyl configurations, Ford said that the ignition control module is no longer a separate component. It is actually integrated into the PCM (power control module)
This is located in the right rear corner of the engine compartment behind the power steering reservoir.
Good Luck, mybunkey>>>>>>>>>>>>>>>>>
POWERTRAIN CONTROL MODULE (PCM) The Powertrain Control Module (PCM) is a preprogrammed, dual microprocessor digital computer that receives various input signals from sensors and switches, and provides the necessary signals to output devices to achieve optimum engine performance conditions.
The immobilizer is inside the PCM. But if your engine does not crank, then the relais in the PDC (power Distribution Center), the Relay in the starter itself too has to be checked.
