Preliminary Checks

NOTE: Only after the following checks have been carried out, should the Multiport Fuel Injection (MFI) circuit diagnosis using a multi-meter or hand held tester begin.

CAUTION: If the engine is misfiring or fails to start within 12 seconds, the cause must be rectified. Failure to do so will result in irreparable damage to the catalyst. After rectification, the engine must be run at 1500 rpm (no load) for 3 minutes to purge any accumulation of fuel in the system.

PRELIMINARY CHECKS
1. Check that the inertia fuel shutoff switch is not tripped.
2. Check that all fuses are OK.
3. Check for ample fuel in fuel tank.
4. Check the air inlet system for any leaks or blockages.
5. Check the high tension spark plug wires for correct firing order, routing and visual damage.
6. Check ignition timing.
