WOW! 10-15mins......

I guess, in the end, what you Really need is to have a good diagnostic tool connected to it to monitor all the sensors while cranking. It would point you what's wrong quickly. Take it to somebody with the proper equipment.

Couple of things you could check, but I don't know how they could cause That kind of delay, would be to see if the HPOP res is empty after it sat for the 12hrs (there's a little plug in the top). What's the fuel filter situation and ability of the pump to refill the housing like? Drain it down through the water separator and cycle the key to see how the pump is refilling.

I would pull off the valve covers and cycle the glowplugs and check the voltage right at each glowplug.... start small.... if its smoking it must be getting fuel i would think the HPOP system must be working. if it was plugged in at 30* i think mine might start without letting the glowplugs cycle, you could try that. i hate to say it but a little starting fluid would rule out sensor issues, be very careful though and let the glow plugs cool off first starting fluid can be risky.
