Inertia fuel shut-off switch

Inertia fuel shut-off switch

The electrical circuit for the fuel pump incorporates an inertia fuel shut-off (IFS) switch which, in the event of a sudden deceleration, breaks the circuit to the fuel pump preventing fuel being delivered to the engine. The IFS switch is situated in the engine compartment, fixed to the bonnet switch bracket which is located on the bulkhead, and must be reset by pressing the rubber top before the engine can be restarted.

WARNING: ALWAYS check for fuel leaks and the integrity of fuel system connections before resetting the switch.

Vehicle diagnostic connector

The diagnostic connector, located on a bracket by the foot pedals, allows engine tuning or fault diagnosis to be carried out using TestBook without disconnecting the ECM harness multiplug.
