Dr Elliot,
Don't confuse priming the pump's internals, ie leaking at the outlet banjo, with additional requirement of priming the injector fuel lines.
If it were my car, this is what I'd do:
1) Be sure that crank TDC on the flywheel corresponds with a suitable bar in the cam timing slot, and any necessary feeler gauge blade inserted to make parallel. Now glance at the cam lobes next to the cam sprocket and be sure they are pointing skywards.Remove locking bar. Now you are safe from mechanical interference, you will not damage the engine without a journey at speed.
2)Disconnect glow plugs Pulling the relay is easiest.
3) Slacken and raise the fuel line nuts off the injectors. dry the joints, and then crank for a couple of seconds. Inspect the joints. Any that become wet, finger tighten the nuts back on. Proceed until all 4 are primed. Crank for a few seconds more. Wipe joints dry on 2, 3 & 4, and nip up with spanner.
4) Slacken line clamp for #1, and #2. Raise #1 injector nut. Remove cam cover, if not still off.
Dry joint, and with ignition on, crank by hand with a spanner or wheel raised in gear, and check for the diesel pulse on the joint.
It should correspond to about 25 degrees before TDC, with #1 cam lobes pointing skywards.
Retighten #1 nut by hand, crank for a few more seconds and fully tighten. Retighten line clamp.
5) At this point, TDC should mean mark on flywheel, slot on cam, and notch on pump sprocket, should line up (nearly) with ridge on pump flange.
6) Reconnect plug relay. Car should start, or show signs of starting with cranking.
7) If you cannot achieve 3)above, then problem lies either within pump or back towards the fuel tank.
