TEST PROCEDURE
1. Turn the engine off.
2. Open the right side engine service access
door.
3. Locate the fuel solenoid, located on top of the
engine.
4. Locate and unplug harness connection 56.
Cut any necessary cable ties. See Figure F.4.
See Wiring Diagram.
5. Check the coil resistance, (black wire to red
wire). The normal resistance is approximately
9 ohms. Check the Resistance between the
black wire and a clean, unpainted chassis
ground. The resistance should be very high,
500,000 Ohms or more. If any of the above
resistance values are incorrect, the solenoid
may be faulty. Replace.

6. Using an external 12VDC supply, apply volt-
age to the coil leads, (black-) to (white+). The
solenoid should activate.
If the solenoid does not operate correctly
when 12VDC is applied, the solenoid may be
defective. Replace.
Re-connect fuel solenoid and replace any
previously removed cable ties.
7. If finished testing, close the engine service
