“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?

With gratitude

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.

That is correct, smelled of diesel but not a drop pumped through it.

It’s amazing how simple these things are!

I will proceed down this list tomorrow and I thank you kindly for the information. I have a replacement filter in hand.

Best,

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.

Worst of it has been addressed and I'm going to finish up today. It's going to get entirely replaced at some point in the near future.
