The troubleshooting will proceed from there. First we have to be sure it is getting fuel or the rest will not matter. We will then check that the HPOP has oil IOT activate the injectors and that they are getting a signal. We may also play with the CPS and GP system but I don't know what temps you are having. If your CPS is dead, it will not fire anyway, but the fuel filter change is relatively cheap and can only help.

When you go to replace the filter, drain it before hand anyway. Pay attention to how the filter and orings come out so the new goes in so it goes in right. Fill with diesel as described, then cap, some like to fill with the thing capped and using the pump but in your case with your problem I recommend filling manually.
If you are just pulling the cap to see if fuel is in there, you don't need to do that. Everytime you have been opening the drain valve and seen fuel tells you some is there. I think you have a big air problem.
Good luck.

When one of ours had run out, and had so much air, we had to cycle the pump several times before it would even begin to fire... and even then took quite a while to run on its own, let alone good,

Well, it may have been getting in there with all of that draining/bleeding. Stop that practice, start with a fresh filter and full bowl and go from there. Keep the tank well above 1/4 full. If the problem persists, we'll move to other sources.
