Larry, no one has mentioned what a job it is to remove the injection pump. Besides removing all fuel lines going to the pump, the oil filter housing will have to be removed. If you just want to check the injection timing, you don't have to remove the inj. pump.You probably have the manual that describes this procedure. If you don't have it, I can scan it and send it to you.
Keep us posted on how things are going.
