“How many enthusiasts even are unaware there's a filter in the injection pump or a thermostat in the oil housing that can lead to issues?”
You have my attention..

Alrighty boys we have proceeded down the troubleshooting ladder here, though I have had very little time but a gorgeous and free weekend ahead. I have no fuel. Pulled injector line, crank, nada.
I do not hear a fuel pump with the key in “prime plugs” mode - believe this is a prime suspect. Is there a relay I can bridge to eliminate that potential point, or shall I proceed immediately to fuel pump replacement?

That is correct, smelled of diesel but not a drop pumped through it.You cracked off an injector line where it connects to the top of an injector, correct?
There is normally no electric fuel pump, unless retrofitted, which isn't a bad idea. Normally you have a pick up pipe at the tank, polyamide fuel line to the fuel filter, fuel line to the mechanically-driven lift pump, and a line to the injection pump. The lift pump is mounted on the side of the engine block near the injection pump. It has a priming lever on the bottom. Your fuel filter is located on the bulkhead above the engine.
Common causes of fuel starvation on these are: blocked pick up pipe due to debris in fuel tank, fuel line leaks, blocked fuel filter, faulty lift pump, and lack of power at / faulty fuel stop solenoid.
I'd crack the line from the lift pump to the injection pump to see if the lift pump is pumping. If it is, then I'd suspect a fuel shut off solenoid issue. If not, I'd suspect the lift pump, fuel filter, or tank pick up. Filter is easy to replace and cross references to many diesel trucks/tractors.
After you get it running, I would circle back when you have time to go through the wiring harness to ensure it’s safe. Electrical fire would be a real shame in a nice looking truck like that.
