Intermittent Engine No Crank (Repair Wiring and Install Wiring Protector)

Some customers/dealers may comment on an intermittent engine no-crank condition with the clutch applied on the above-listed vehicles.

A pinched/damaged clutch position switch wire (1) at the base of the steering column may cause this condition. The main instrument panel (IP) electrical harness sweeps past a support brace at the base of the steering column. The edge of this brace is very sharp and the harness containing the clutch position wire can contact and rub against the brace. If the gray (GRA) clutch position wire, circuit number 379 (RPO L18) or 808 (RPO LG5) gets pinched and causes a short, the vehicle will experience a no-crank condition.

Verify the cause by inspecting the gray clutch position switch wire. If this wire is pinched and/or shows damage, use the following procedure to correct the condition. If this gray wire shows no damage, diagnose and locate other possible causes of the condition.

1. Pull the wiring harness away from the steering column support brace.
2. Repair any pinched/damaged wiring. Refer to Wiring Repairs in the Wiring Systems sub-section of the Service Information.
3. Place wiring protector (1), P/N 7828271, over the sharp edge of the support brace. This protector comes in a 247 mm (9.71 in) length. The protector may need to be cut in half to fit over the edge of the support brace flange.
4. Reposition and secure the wiring harness away from the steering column support brace.
