Ignition System: Testing and Inspection

ON-VEHICLE INSPECTION

NOTE: "Cold" and "Hot" in these sentences express the temperature of the coils themselves. "Cold" is from -10 °C (14 °F) to 50 °C (122 °F) and "Hot" is from 50 °C (122 °F) to 100 °C (212 °F).

INSPECT IGNITERS AND SPARK TEST

Check that the spark occurs.
1. Disconnect the high-tension cord from the spark plug.
2. Remove the spark plug.
3. Install the spark plug to the ignition cord.
4. Ground the spark plug.
5. See if spark occurs while engine is being cranked.

NOTE: To prevent gasoline from being injected from injectors during this test, crank the engine for no more than 5 - 10 seconds at time.





If the spark does not occur, do the test as shown.
