They have a mechanical injection pump I'd start there

i dont have a clue about it. i traded for the truck because it has 5 ton military axles under it with four wheel steer. i want to keep the diesel as long as i can. where is the injection pump located at ? and how hard is it to find one?:thankyou2:

go out and buy your self a chiltons manual , you will find there is a lot of information in there . I would bet it is a stuck govener spring assembly in the top of the pump. If it happens and you cant shut it off there is a pink 10 gage wire going to the center of the pump that will shut the pump down thus thge truck . The pump is located in the valley of the block up front. Look at the fuel lines and fallow them up front you will see a spider lookinf head with 8 li nes , that is the pump

thanks will stop and get a manual tomorrow on the way to work. when it gets stuck the key wont even cut it off. i am planning on building the truck to ride around and the fram and do a little rockcrawling with it. thats why i wanted to keep the diesel in it. it will run on off camber angles. :thankyou2:
