Examination of inoperative diesel injection pump fuel shut off solenoids reveals that a large percentage of this condition is caused by an accumulation of
metal particles on the operating mechanism. The magnetic effect of the solenoid causes this accumulation. Before replacing any solenoids, blow off the
debris with compressed air and check for proper operation by applying 12 volts to the terminal and grounding the cover.
