.... fuel is getting to and through the injectors, although that hasn't been tested while the injectors are in the block, so the diesel they are getting might not have enough pressure to open them when compression comes into the equation.

If that isn't the case, and you have the new style black pump, try pumping it at rest and see if you feel any resistance. I wager you may discover you're pumping air.

I've got a black hand pump, a bit like a mini-donut, right up by the main diesel filter. Quite firm to pump, and as the pump expands again, you see diesel getting sucked into inline filter, as you would expect.

...... exactly the words I want to hear, a prognosis that matches the symptoms.
If it is an air leak, it's going to be tricky to track down, I can replace what diesel lines there are after the inline filter with plastic lines I guess.

I changed all the filters a few months ago.
It could be an airlock however, caused by originally not having pre-glow ( a couple of wires have been tightened since the car first wouldn't start ) followed by flooding, followed by random acts of troubleshooting. Hopefully the tow start tomorrow will get it up and running and purge an air lock should it exist.
