IPR Short?

2000 F250, 7.3, auto trans. Intial findings were after a no start, no smoke, PCM would not communicate. Replaced PCM. Still no start. At engine Crank 165 RPM, 10.8 Volts, ICP starts at 600 + and goes to 2550, IPR 14.7 and climbs. Same result with ICP Unplugged.
Started checking wires for shorts. (IPR UNPLUGGED)On pin A (Red Wire) of IPR connector resistance is 250 Ohms, Pin B 10K ohms. When I unplug the PCM pin A reads Open.

So far everything else (IDM Wiring, injectors, glow plugs and other sensors check OK)

I get WTS light

Could this be another Bad PCM? It is brand new

Thanks For The Help,

Hello Mark,
I am obviously behind in finding the problem to my not start truck. I am curious about how you get all these values... I am in south america and have no access to a code reading computer, could you suggest some troubleshooting I can do with a standard multimeter? You mentioned some resistances on some wires and pins.

PS: My post with a description of my problem was posted just before or after yours on the same forum section.
