I have finally narrowed my shutoff problem down to the where the valve on the injection pump. The valve is stuck....I can get it to shut off with the mitey-vac but it takes 30-40 lb of pressure and it does hold the pressure which leads me to think that a simple cleaning is all it needs.....I cannot get it off however. I have the ALDA removed to get to the rear nut(found out the ALDA is shot in the process) and it is stuck under a plastic unit to the front engine side of it. Two wires come out of the plastic unit and it has a screw similar to the headlight deal....I am not sure how to take the plastic piece off and cannot find it in the online service manual any help would be appreciated and If you need pics I will get them tomorrow....Thank you
