you will need the engine turned on to the run position to deactivate the stop system in the pump
injector lines are bled at the injectors
loosen the nut off and crank the engine over until the diesel drops are seen

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).

Try looking at fuel pump, check fuses, test for power to pump, is power to pump the more than likely failed pump.

G'day...I want to remove/replace the injector pump on a ford 5000 tractor


Fuel systems can be a bit tricky, especially if it is all mechanical, which means you will have to time it. I would make sure you get all the air out of the system before you go with the pump. Diesel fuel systems work at very high pressures as well so be safe.

I have a ford 8000 tractor with a mechanical governed minimec inline 6 injection pump. the tractor was running at 85% throttle, i idled it back & it shut down. will not start now. have changed filters,...


Sean if you idled it back on a mechanically governed engine you have shut the fuel off to the injectors... turn it back up slowly and possibly crack the bleeders on the injectors to make sure you haven't sucked any air,good luck!
