Ignition Coil

Ensure ignition is off. Disconnect ignition coil wiring. Measure primary resistance between terminals "C" and "E". See Fig 1 . Measure secondary resistance between terminals "C" and "D". Measure insulation resistance between terminals "C" and body ground.
Make sure resistance is within specification. Refer to the IGNITION COIL RESISTANCE (NON-HEI SYSTEMS) table. Replace coil if resistance is not within specification.
