2000 7.3 failure to start!
Let me distill this into it's component parts: Truck won't start and I have done the following:
new glow plug relay, glow plugs read 0.9 ohms, fuel in the fuel filter housing was reddish brown, drained all fuel from truck and refilled, black smoke when cranking, tach jumps when turning engine over, 2 new batteries, no blown fuses, disconnected glow plugs and ethered engine and it fires then dies, no codes on OBD II. Any suggestions from anyone?

You running heating oil in that thing? Road legal diesel is light green. You might have to force it to run for a little bit more before that "reddish brown" fuel gets worked out of the fuel injectors. By the way WD-40 is a MUCH safer starter booster than ether, and it will not dry out the upper cylinders either.

Had a Ford mechanic come to the house and run the OBD II codes. Showed
high____?_____bank 1,( most likely a loose injector connection at the valve cover connector), good HPOP pressure, (1450 psi) all injectors tested good electrically, rpm when cranking 135 (about 25 too low), some problem with IDM, and possible problem with PCM. He believes that the engine should run based on the electronic tests. He thinks that the problem lies in low compression. Engine has close to 400K on it. Time for a new engine! Any sugestions where to get one?

The use of heating oil (if that is what it actually is), isn't the problem. The only difference between heating oil and diesel fuel is the red dye. Was he a Ford Diesel mechanic? I question his dismissal of the "some problem with IDM" code. Every symptom you describe seems to indicate no fuel to the cylinders. A bad IDM can cause the injectors not to fire. It is possible also, the low cranking rpm could have something to do with it, but it should have continued to run after ethering (throw that stuff in the trash, BTW) the engine, if it were indeed getting fuel.

He's getting fuel Pikachu, his first post says black smoke when cranking. I have to agree with the low rpm during cranking. Get the cranking speed back up and I'll bet it will start. New batteries, starter maybe. I really doubt that the compression failed in all the cylinders all at once.
Edit: Hmmmm, yeah it should have continued to run once started.
