To check that spark is occurring at the spark plugs, perform this spark test.
- Disconnect the spark plug wire from a spark plug.
- Remove the spark plug.
- Reconnect spark plug wire and ground the spark plug.
- Check for spark while cranking the engine. Do not crank the engine for than 1 or 2 seconds to prevent the engine from starting. If it does start, turn it off immediately.
If no spark occurs, continue the test as follows:
- Check the connections of the ignition coil, ignitor and distributor connectors.
- Check the resistance of the spark plug wires.
- Check the power supply to the ignition coil. Turn the ignition ON and check for battery voltage at the positive terminal of the ignition coil.
Check the ignition coil primary resistance (cold).
- 0.4-0.5- on all except Canada and wagon
- 1.2-1.5- on Canada and wagon
Check the ignition coil secondary resistance (cold).
- 7.7-10.4k- on all Canada, wagons and on 1984-1986 sedans
- 10.2-13.8k- on 1987-1994 U.S sedans
- Check the air gap between the pick-up coil and the signal rotor teeth as follows:
- Turn the engine over (you may use a socket wrench on the front pulley bolt to do this) until the projection on the pickup coil is directly opposite the signal rotor tooth.
- Get a non-ferrous (paper, brass, or plastic) feeler gauge of 0.3mm (0.012 in.), and insert it into the pick-up coil air gap. DO NOT use an ordinary metal feeler gauge! The gauge should just touch either side of the gap. The permissible range is 0.2-0.4mm (0.008-0.016 in.).
The air gap is not adjustable. If the gap is not within specifications, the pick-up coil assembly must be replaced.
- Check the pick-up coil resistance (cold).
- 1984-1990 3A-C and 3E - 140-180-
- 1990 3E-E - G and NE pick-up coil resistance 140-180-
- 1991 3E-E - NE pick-up coil resistance 410-510-
- 1992-1994 3E-E - NE pick-up coil resistance 370-530-
- If the ignition system still fails to produce a spark, replace the ignitor.
