Diagnosis and Testing


To test the ignition system, perform the test procedures in a particular sequence. Start with the secondary spark test, commence to the coil test (located under the coil procedures later in this section) and, finally, perform the failure-to-start test. Performing the tests in this order will narrow down the ignition system problem in the easiest manner.


The Direct Ignition System generates approximately 40,000 volts. Personal injury could result from contact with this system.

Since there are 2 independent coils in the assembly, each coil must be checked individually. Cylinders 1 and 4, and 2 and 3 are grouped together.

  1. Remove the cable from the No. 1 spark plug, then insert a clean spark plug into the spark plug boot.

Due to the high secondary voltage and risk of electrical shock, it is advisable to wrap a thick, dry cloth around the boot before grasping it.

Spark plug wire damage may occur if the spark plug is moved more than1/4in. (6mm) away from the engine ground.

  1. Ground the plug to the engine (touch the spark plug metal body to the engine block or other piece of metal on the car).
  3. Crank the engine and look for a strong, blue spark across the electrodes of the spark plug.
  5. Repeat the test for the three remaining cylinders. If there is no spark during all cylinder tests, refer to the failure-to-start test. If one or more tests indicate irregular, weak or no spark, refer to the coil test.


See Figure 1

Before proceeding with this test, refer to the testing procedures for the ignition coil, later in this section.

  1. Using a Digital Volt/Ohmmeter (DVOM) measure the voltage from the negative (-) battery terminal to the positive (+) battery terminal. The voltage should be at least 12.66 volts. This amount of voltage is necessary for an accurate inspection of the system.
  3. Detach the ignition coil harness connector.

  1. Connect a suitable test light to the B+ (battery voltage) terminal of the ignition coil electrical connector and ground. The center terminal of the connector supplies battery voltage.
  3. Turn the ignition key to the ON position. The test light should flash ON and then OFF. Leave the ignition key ON .
    1. If the test light flashes momentarily, the PCM grounded the ASD relay. Proceed to the next step.
    3. If the test light did not flash, the ASD relay did not energize. This is caused by either the relay or one of the relay circuits.

  5. Crank the engine. (If the key was placed in the OFF positio
