1968 ford 2000 tractor 3 cylinders number 1 cylinder isn't getting fuel from injector pump the other 2 are is pump bad or not primed right
You need to ensure that here are no vacuum leaks in the line from the tank to the lift pump, the lift pump which looks very similar to a car petrol pump must be in good working order ie able to pump the minimum pressure and volume at cranking speed and idle speed.
If the lift pump is not working properly it will cause cavitation at the injector pump that will cause low pressure bubbles on the intake of the injector pump. If you have a good lift pump and there are no vacuum leaks between the tank and the lift pump then it may be down to bleeding the air out of the injector lines first at the pump, and then at the end of the injector lines (be very careful the diesel is at 170 to 175 times atmospheric pressure which is about 2500 pounds per square inch (which can penetrate skin deeply and even bone). Most of the Ford tractors use a rotary injection pump. Having only one cylinder not pressurizing is extremely unusual, try swapping the injectors between cylinders to see if it is a faulty injector, making sure to use new or at least anneal the old copper sealing washers and tension the injectors evenly with a tension wrench to correct torque. If the misfire then follows the injector it means your need the injectors servicing. New needles & nozzles for injectors is a lot cheaper than a new or rebuilt rotary injection pump. Please advise if it’s an inline pump. (which I doubt they were rare because they cost more).
