Preliminary Checks

CAUTION: If 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 catalysts. After rectification, the engine must be run at 1500 RPM (no load) for 3 minutes to purge any accumulation of fuel in the system.

Check that the inertia fuel shutoff switch is not tripped. Inertial fuel shutoff switch is located beneath left front seat. See Fig 1 .
Check main and fuel pump relay fuses.
Check for ample fuel in tank.
Check air inlet system for possible leaks into the intake manifold.
Check spark plug wires for correct firing order, routing and visual damage. See appropriate SPECIFICATIONS article.
Check ignition timing. See appropriate SPECIFICATIONS article.

Only when the above checks have been carried out, should circuit diagnosis begin.
