N14 Base Engine Troubleshooting and Repair Manual – 005-043   Fuel Shutoff Valve

Remove the wire. Make sure the remaining wire connection nut is tight. Tighten the nut.

Make sure the post is tight and secure in the coil.

NOTE: Only single post coils can be used on the CELECT™ fuel system. Two post coils will interfere with the cooling line.

Use a wire brush to clean any corrosion from the coil terminal.

CAUTION  This must be the only wire connected to the shutoff valve.

Connect the wire. Make sure the shutoff valve coil is the correct voltage.

The coil voltage and part number are cast into the terminal connection end of the coil.

Turn the vehicle keyswitch to the “ON” position.

Check the voltage to the coil with a multimeter, Part Number 3377161, or equivalent.

The voltage must be the same as the battery voltage.

Turn the vehicle keyswitch to the “OFF” position.

Make sure the coil wire is not connected before checking the coil resistance.

Check the coil resistance with a multimeter.

Replace the coil if the resistance does not meet the specifications.

Turn the vehicle keyswitch to the “ON” position. Listen for the valve to “click” when the wire is touched to the coil terminal. If the valve does not “click”, repair or replace the fuel shutoff valve.

Remove the coil housing and the fuel shield. Discard the o-ring.

Remove the spring washer, valve disc, actuator disc, and actuator spacer from the valve housing. Discard the o-ring.

WARNING  When using solvents, acids, or alkaline materials for cleaning, follow the manufacturer’s recommendations for use. Wear goggles and protective clothing to reduce the possibility of personal injury.

WARNING  Some solvents are flammable and toxic. Read the manufacturer’s instructions before using.

WARNING  Wear appropriate eye and face protection when using compressed air. Flying debris and dirt can cause personal injury.

NOTE: Do not get the coil wet with solvent. Clean the coil with a dry cloth. Polish the coil face with a 200 grit emery cloth on a flat surface.

Clean all of the parts except the coil assembly in solvent.

Dry with compressed air.

Visually check the valve disc, valve seal, and actuator disc for dirt, metal parts, bonding separation, corrosion, cracks or wear. Replace if necessary.

Measure the coil resistance with a multimeter.

Replace the coil if the resistance does not meet the specifications.

NOTE: If the coil assembly shows 0 ohms, there is an electrical short in the coil.

Install these parts as follows.

Install the spacer (7) o-ring groove toward the coil.

Install the actuator disc (5) with the cup side toward the coil.

Install the spring washer (3) with the cup side toward the coil.

Align the actuator disc (5), spacer (7), and valve disc (4) on the front cover (8). Install a new o-ring (6).

Put the spring washer (3) on the valve disc (4), cavity side up, in a position around the valve locator.

Install the fuel shield (2) and coil (1) on the front cover (8). Install a new o-ring and tighten the capscrews.
