10） FUEL SHUTOFF SOLENOID
Description and Location
The fuel shutoff solenoid, 1, is located on
the right side of the engine, threaded into the
rear of the fuel injection pump, 2. The fuel
shutoff solenoid contains a spring-loaded
plunger that pushes the injection pump
control rack to the closed (shut-off) position
when the solenoid is not energized. When
the key switch is turned to the "ON" or
"START" position, the safety stop relay
closes completing the circuit that energizes
the solenoid. This retracts the plunger from
the injection pump, and the injection pump
control rack moves into the position that
allows the engine to start.
