after the solenoid is removed, did you try pulling back the plastic insert inside the fuel injector pump??? see if its stuck
CK25 will not start

If you are on the right side of the tractor, looking at the injector pump, the lever coming out of the "side" of the IP, that the solenoid activates, should be all the way forward to turn on the fuel. Or another way to look at it is the shaft coming out of the "side" of the IP, that the lever is attached to, should be rotated all the way "clockwise" for fuel on. You should be able to move it by hand back and forth. The lever on "top" of the IP is the throttle. This should move by the throttle control at the dash or with your hand.
You had advised you have fuel flowing up to the IP. This flow would be supplied by the fuel/lift pump that is located between the tank and filter and is mounted to the right side of the engine to the left and below the filter. It's about 2 1/2" dia. with about eight little screws on it's flat end. It's not much of a fuel flow but the fuel will flow. With the steel injector lines cracked at the top of the IP, as you did, and the IP fuel shut off lever all the way in the fuel on position, the cranking should prime the IP and push fuel out of where you cracked the connections at the top of the IP. If you can get fuel there, tighten these, then crack open the steel lines at the injectors to purge any air from the steel lines. If nothing comes out of the steel lines you cracked open, it seems like the IP is gone.
As mentioned, if it does start up at wide open throttle, you're going to have starve it of fuel or air to stop it. Disconnecting the battery won't stop it. Diesels just need fuel, air, and compression to run once they are started.

the plastic insert is what controls whether any fuel flows thru the pump. The solenoid pushes it (to shut off fuel flow) and the spring loaded (start spring) forces it back open. If the internal plastic plunger is stuck, it will prevent fuel from flowing thru fuel injector pump.
Im not talking about the plunger on the stop solenoid, im referring to the internal white plastic plunger
With that internal insert, if the stop solenoid is removed, the insert should be pushed out towards the hole that the stop solenoid is installed in. You should be able to lightly push it back in. This would be simulating what the stop solenoid is doing to stop the engine. When you turn on the key, the stop solenoid retracts and allows this internal plunger to expand...thus allowing fuel into the Injector pump.
also, did you ever try to bleed the pump??

The plastic plunger moves freely back and forth. However, when the solenoid is removed it is not push out as if it were spring loaded. I would have to manually move it with my fingers which I did. No I have not tried bleeding the pump. How is that done?
Victor W:
Not sure what the lever coming out the side is. The throttle is easily indentified since it has cables going back the the foot petal and hand lever. The other lever you are referring to I do not make out. There is a lever on top of the pump near towards the solenoid. This lever is spring control and is always up against a metal stop. I assumed this was some sort of manual fuel cut off. I will try to take a pic tomorrow of the set up.
Thank you both.

If you pull the lever out by hand, can you start the tractor??? mind you you will have to push the plunger back in to stop it.

Here are the instructions for bleeding on the DK series injectors, but ive been told the CK are the same.
The line drawing on 1st picture shows the bleeding bolt . There are also step by step bleeding instructions
Hope this helps
in 3.5.2 (Page 4) theres a step by step list how the stop solenoid functions.
