Ignition Checks: IGNITOR

WARNING: This page is about a different car, the 1994 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ensure coil and power source are okay before checking ignitor. Disconnect coil ignitor connector. Install Ignitor Checker (49 F018 002) and Adapter Harness (49 N018 001). Connect the ignitor checker and adapter between the ignitor and wiring harness, connect the power leads to the battery.
  2. Turn ignition on. Disconnect the high-tension coil lead from the distributor and hold it about 1/4" from ground. Flip the SW2 on and off, and verify a strong Blue spark is discharged from lead. If spark is weak in color, replace the coil. If no spark is present, check battery feed, main fuse, ignition switch and fusible links. Repair or replace as necessary.
    CAUTION: DO NOT hold the SW2 switch on longer than one second or igniter will be damaged.
  3. Turn ignition on. Using voltmeter, check voltage on Black wire of adapter harness. Flip SW2 switch on and off. Verify voltmeter fluctuates. If voltmeter does not fluctuate, replace ignitor and retest.
