    1. Ensure the ignition is off.
    2.  
    3. Perform a visual inspection of the coil pack. If it is cracked or leaking oil, the coil pack is defective and should be replaced.
    4.  
    5. Disconnect the coil pack electrical harness.
    6.  
    7. Label and disconnect the spark plug wires.
    8.  
    9. Using an ohmmeter, measure the coil primary resistance between terminals 2-3 (coils for cylinders 1-4) and terminals 1-3 (coils for cylinders 2-3). Resistance should be 0.45-0.55 ohms.
    10.  
    11. Measure the coil secondary resistance between the cylinder No. 1-No. 4 high tension terminals and the cylinder No. 2-No. 3 high tension terminals. Resistance should be 10.3-13.9 kilo-ohms.
    12.  
    13. If resistance is not within specification or the test results in an open or shorted circuit, replace the coil pack.

    1. Ensure the ignition is off.
    2.  
    3. Perform a visual inspection of the coil pack. If it is cracked or leaking oil, the coil pack is defective and should be replaced.
    4.  
    5. Disconnect the coil pack electrical harness.
    6.  
    7. Label and disconnect the spark plug wires.
    8.  
    9. Using an ohmmeter, measure the coil primary resistance between terminals 2-4 (coils for cylinders 1-4) and terminals 1-4 (coils for cylinders 2-3). Resistance should be 0.77-0.95 ohms.
    10.  
    11. Measure the coil secondary resistance between the cylinder No. 1-No. 4 high tension terminals and the cylinder No. 2-No. 3 high tension terminals. Resistance should be 10.3-13.9 kilo-ohms.
    12.  
    13. If resistance is not within specification or the test results in an open or shorted circuit, replace the coil pack.

    6.  
    7. Label and disconnect the spark plug wires.
    8.  
    9. Using an ohmmeter, measure the coil primary resistance between terminals 1-2 of each individual ignition coil. Resistance should be 0.45-0.55 ohms.
    10.  
    11. Measure the coil secondary resistance between the cylinder high tension terminals. Resistance should be 10.3-13.9 kilo-ohms.
    12.  
    13. If resistance is not within specification or the test results in an open or shorted circuit, replace the coil pack.
