The fuel cut selenoid is on the back of the injection pump. It is the round selenoid in the head of the injection pump. THe head is the square black block on the back of the pump. It takes a few minutes to remove it. I just used a large adjustable wrench.

Those wires on the top of the fuel filter are for the fuel heater element.

To me it sounds like you have a timing issue. Also, when was the last time your injection pump rebuilt? These pumps are prone to sediment buildup and carrosion in the bottom end of the pump which will effect timing.
