Disconnect the starter interlock switch connector.
Inspect for continuity between terminals of the starter interlock switch using an ohmmeter. See Fig 1 . There should be continuity with the clutch pedal depressed between (B) and (C) terminals, and there should not be continuity when released. If not as specified, replace the starter interlock switch.
