Examination
1. Disconnect the ignition distributor electrical connector.
2. Using an ohmmeter, check the resistance between the pulse sensor contacts.
3. If the resistance differs from the required values, replace the ignition distributor.
Checking the Gap of the Pulse Sensor
1. Remove the ground wire from the battery.
2. Remove the ignition distributor from the engine.
3. Using a feeler blade, check the clearance between the rotor and the pulse generator. If the gap is more than acceptable, replace the ignition distributor, as the gap is not adjustable.
