Fuel Stop Solenoid (GM 3000–D)

The fuel stop solenoid is located on the front end of the injection pump, which is on the right side of the engine. Its has a black wire connected to it that leads to a con­ nector with a white and orange wire. The solenoid is powered from the white wire (Fig. 25).

In Place Testing

Note: Prior to taking small resistance readings with a digital multimeter, short the test leads together. The me­ ter will display a small resistance value (usually 0.5 ohms or less). This resistance is due to the internal re­ sistance of the meter and test leads. Subtract this value from from the measured value of the component you are testing.

1.Disconnect black wire from the solenoid.

2.Using a digital multimeter, ground one lead to the base of the solenoid and connect the other to the sole­ noid terminal.

3.The resistance should be approximately 8.0 ohms.

Live testing

1. Remove black wire from the solenoid.

Note: The solenoid may be removed from the engine or tested in place.

2.Connect a positive (+) test lead from a 12 VDC source to the solenoid terminal.

3.Touch a negative (–) test lead from the 12 VDC source to the solenoid body. The plunger should retract making an audible ”click”.
