D 250 Pickup L6-359 5.9L DSL (1992)
Fuel Cut Solenoid: Testing and Inspection
NOTE: Check all connections for loose or corroded connections and for broken wires.
Remove the valve. Ground the valve and connect 12 volts DC to the terminal and observe plunger movement.
The valve does not make a very audible sound when actuated, but it can be checked with a volt or ohm meter for the following values:
Shut Down Values
Operating Voltage - 12 Volt DC
Minimum Voltage to Open - 10 Volt DC
Resistance Ohms - 7.4 + 0.5
Peak Amperes - 2
CAUTION: Do not connect the electrical wire to the solenoid when the plunger has been removed. Without the plunger the valve can be damaged.
Malfunctioning valves can be diagnosed by removing the plunger and spring, then reinstall the solenoid.
WARNING: If the plunger and spring is removed from the solenoid, the engine will start when cranked. Make sure the transmission is in Park or
Neutral with the parking brake set.
