So, I started this odyssey attempting to get the AC compressor running. The radiator and condenser fans were and are running. However the compressor relay in the under hood fuse box was not energizing the compressor clutch circuit. I believe/d the problem was that the energizing circuit was not getting a ground to close the relay. In trying to manually ground that circuit I shorted at the no. 17 fuse ( I have the full FSM). After replacing the fuse the fans did not run. I get voltage to all the under dash fuses except for 13 PGM-FI main relay, and 31 - integrated control unit, PCM (A:T), PGM-FI Main Relay. However at first I was not getting the fuel pump activation, so I bought a newer ECU and the Fuel Pump became active. However, I reinstalled the old ECU and the fuel pump was still activated. I was getting voltage at all the relay connections, and they all worked, and the Compressor clutch relay was getting voltage but still the relay was not switching and energizing the compressor clutch circuit. So I suspected the Main Relay unit, although the fuel pump was running. Anyway I removed it and resoldered all the connections. The Main relay seems to be fine.
So now the issue is the car does not start, no spark. No start, no compressor clutch activation with the AC turned on, and both fans are running. The car started and ran fine with the old ECU before whatever then happened. It does not start with the new ECU. All the other circuits seem fine except the Ignition key light and the key in engine off chime, which are energized by fuse 43, which has 12v, but those are not working.Those items run into the Integrated Control Circuit. So, probably sumpn simple but I ain't seeing it. I have checked the fuses in both boxes umpteen times. All have voltage except 13 and 31 even though the main relay is powering the fuel pump, which it seems it should not be if 13 has no voltage. So I propose to hot wire the 13 and 31 fuse connectors, or send 12v to the ignition circuit or both. Where is it recommended to hot wire to to energize the coil and Ignition Control Module. By the way, if I manually activate the compressor clutch relay I can hear the clutch clicking as it should. I have not checked the integrated control unit where are the ignition key light timer, ignition key light, and key interlock solenoid, among other stuff. The key in EO was working ok before. All the lights work, ceiling lights too. So I really need to get the engine running first.

 

Just an update on this problem; turns out it was a bad ECU/PCM. I replaced the computer and it appears everything is working including the AC compressor. I will be filling the AC with gas as soon as the weather improves. It has been raining and cold all thru Christmas and New Years.
My present concern is that the motor bogs and dies when put into gear; it is the all time 4wd AT. It really looks like a ton more of money is needed just to get this beast saleable.
