Did you check what I suggested Bill?
Here's another suggestion. The Quantum self primes prertty readily both fuel
and coolant system not like the nasty little Rabbits. Sorry I digress!!
1) Remove your steel fuel lines.
2) place some rags over the coolant hoses.
3) Check that fuel cycles back to the tank. Crank engine with solenoid and
glowplug power disconnected If you don't have that then you have no chance
4)If you do have fuel going back to the tank, then reconnect solenoid and
return fuel pipe. [remember leave injector rubber lines alone [they tell you
nothing !] At this point I'd expect to see fuel leaking out of pump fuel
line outputs. If you don't then problem is still either solenoid, or pump
5)You do have diesel in the tank don't you?
6) Runaway from the pump is more common now that people have been turning up
the max fuel too far, by removing protective sleeve. Granted only not
turnoff-able if solenoid fails open, or revs go so high that the pressure
drop across airfilter gets significant enough to suck everything out of the
