Inertia Switch Test

CAUTION: DO NOT  reset the inertia switch until the complete fuel system has been inspected for leaks.

In event of a collision, electrical contacts in inertia switch open and fuel pump automatically shuts off. Fuel pump will shut off even if engine does not stop running. The engine, however, will stop a few seconds after fuel pump stops. It is not possible to restart engine until inertia switch is manually reset. Inertia switch is located behind instrument panel. To reset inertia switch, depress button on top of switch.
