Is there fuel in the bowl ? and can you see its passing through when priming with the hand pump ?

The feed pump may be stuck then. ITs a big slotted cap, you need either a very big screwdriver or a piece of 2mm metal with a vise grip to turn it open. Then see if the plunger moves freely.
Okay - here is where we are at.
Took the big screw out of the fuel pump and the plunger was stuck underneath. Got it out, cleaned it up, reinstalled it, and how the fuel pump works. We've got all kinds of fuel coming out of the pump, and up through the bleeder screws on the side of the injector pump.
However, now fuel isn't coming through the injector pump to the lines up to the injector.
Any ideas on the injector pump? Is there anything to check in it or do I need to take it off and take it to a place that works on pumps?
This tractor came off an auction sale, and it wasn't running when we bought it, but the guy claimed it ran when parked a couple years back.

Sounds like the rack may be siezed in the pump. You can take the side plate off the side of the pump, and see if the pump elements are moving when you move the governor linkage to high idle. If nothing moves, the rack is stuck. You can't see the rack it is behind the pump elements.
You can spray all the internals with a penetrating fluid, and force it with a screw driver or something to get it moving the elements rotate anti-clockwise from the top where the little screws are that clamp the pump elements), fill the pump housing and governor housing up with diesel, and run it. But be very mindful that if you start it before you get it free enough, the engine may run away, and you'll end up with bits of engine on the ground, and possibly in you
So if you do decide to free it up yourself, take the air intake hose off the inlet manifold, and have something solid ready to block it off if things go bad, quickly!!
Once you have it all freed up, and flush the housings a few times with diesel, don't forget to drain them both, and refill with clean engine oil.
Once, again, DO NOT start it until you have the rack moving nice and freely! Spray everything you can with a good penetrant, and let it sit a while, and repeat a few times before you try forcing anything.
Good luck!

Agripower 5000 is this a 5011 or 5211 ?? and when did the fuel pumps with engine fed lubrication came ? 5011 or 5211 ?
If it has an open connection the diesel fuel will run into the crankcase quickly. But penetrating fluid and fiddling with the rack and later a screwdriver, should get you pretty far.
