Tractor Repair: JD 450 type T5E3M fuel injector problem, fuel injection pump, roosa master

Question
Tractor was running good for 3 hours and then died.  Have a Roosa Master fuel injection pump CBC431-2AL. I pulled the inlet line to the pump and have plenty of fuel. Checked to be sure the solenoid had power. Cracked injection lines at the engine block.  Still no fuel. What can you suggest to do next?  Thank you.

Answer
I think either your pump is bad or the rack that controls the fuel shutoff solenoid is stuck. Problem is that pump is a real odd ball. My advice take it off and take it to a pump shop. If it is real bad you are going to have to change it over to the other style pump. If you go to a dealer they will sort out all the subs for that model of pump.
