3. Measure the ignition coil resistance.
Replace if out of specification.
Checking the ECM
1. Disconnect an ignition coil coupler.
2. Connect the test harness (2 pins) to the
ignition coil.
3. Measure the ECM output peak voltage. If
below specification, measure the pulser
coil output peak voltage. Replace the
ECM if the output peak voltage of the
pulser coil is above specification.
Checking the pulser coil
1. Remove the flywheel magnet cover and
disconnect the pulser coil coupler.
2. Connect the test harness (2 pins) to the
pulser coil.
3. Measure the pulser coil output peak volt-
age. Replace the pulser coil if below
specification.
