It may be biodiesel.
Wait to start light comes on when key is cycled, goes out after about one second.

With the fact that it comes on is a good thing, that means the pcm is atleast doing something. I believe it determines glow plug time from an oil temp sensor, not 100% on that though.
With A/E you should also be able to monitor how long the pcm is commanding the glow plugs and if the relay is energized. Or atleast my snap-on does.

About how much oil should I see coming out of the injectors while cranking?since the valve covers are off, crank it over and look for oil coming from each injector spout. If there is oil flowing from all 8 injectors then you can eliminate the HPOP, IDM, and electrical side of the no start problem.
Next, jump the large terminals on the glow plug relay for at least 15 seconds prior to starting (a jumper cable clamp works good for this) and then try starting the engine.
Fuel filter has not been out. Black fuel would suggest oil in the fuel, and thus badly blown injector o-rings?I would honestly check the oil pressure in the head with a manual gauge if at all possible.
I don't remember what all you said you looked at when you first started trying to diagnose. Did you saw you had the fuel filter out? If so was the fuel black?

I wouldn’t think it would be possible to build 3500 psi from 150 rpm either, but I’m not too familiar with the system. Somehow I am having a heck of a time finding an answer to the question of why my ICP signal reading would climb like that. Especially given my seeming lack of a sensor reading at the connector itself. I agree with your earlier post, I think it’s time to collect the materials to get a manual gauge reading and put this uncertainty to rest.Yes the black fuel filter would indicate a blown center injector o-ring. Could also watch around the base of injector for oil coming up around any of them.
I may be wrong on this but I didn't think this system was capable of building that kind of pressure at cranking speed.
