Have a D600 with a very odd problem.
Good fuel flow and pressure at the injection pump inlet but the outlets only dribble out fuel with no pressure at all, even after bleeding the system. Injectors are leaking compression which really doesn't help with bleeding but lack of fuel pressure seems like the bigger issue. The tractor has been sitting for a long time so I'm starting to think that maybe something is seized up internally.
You would think that it would at least do something, right? The pump plungers are moving on the bottom but it almost acts like they aren't even being pressed.

I had a D722 the rack was stuck from setting. Pulled the pump and nozzles had them tested. Shop went thru the pump and checked nozzles. $150 later it fired right up and runs just fine.
