I put a new glow plug relay (I think it's called) a few months before it went down. I really could not tell that it made a difference. Maybe they are just shot.

Have you checked to make sure your GPR is working correctly?

Just take a digital volt ohm meter and place it across both the big terminals (one meter probe on each) on the GPR as someone turns the key on in the (cold) truck (but not start it). You should see the voltage drop from whatever your batteries are putting out, to zero. If it goes to zero (not 1 or 2 etc) then the relay is working fine. If you still read any voltage then the GPR is not working correctly. If you have problems it is either the GPR is bad or it is not recovering the correct signal to turn on the glow plugs.

You said the hpop reservoir is empty. Did you drain it or did it drain its self? If you have a leak on the high pressure oil system it is going to be very hard to start cold and even worse hot and it will run like crap

At this point there are several things going on. You say that it died years ago and never fired again.

Can you check for codes?
Also, unplug the fuel bowl heater and check that line to see if the fuse is blown. (Can not remember which fuse it is) if the fuse is blown, put in a new one and leave unplugged.

If you have a bad CPS it may not start/ run.....

What is you oil level? If you get too low, the injectors will close (held open by oil pressure) and the truck will not run. The HPOP having no oil in it is something to look into.

You will need your batteries in top charge mode because you will be cranking on and off for a while to get the oil pressure biult up and get fuel to and into the rails.

What is your fuel pressure, as the fuel filter in the bowl or tank may be clogged.
