Spark Check

WARNING: This page is about a different variant/trim than selected.
  1. Perform self diagnostic QUICK TEST in the TESTS W/CODES article to check for ignition-related fault codes, and repair as necessary. If no fault codes are retrieved, check ignition system wiring harness for damage or loose connectors. See the WIRING DIAGRAMS article. Clean or repair connectors as necessary.
  2. If wiring/connectors okay, use Neon Bulb Spark Tester (D89P-6666-A) to check for spark at each spark plug wire while cranking engine. If spark strong and consistent at each spark plug (one spark per crankshaft revolution), ignition system okay. If spark is not present, go to CIRCUIT TEST A in TESTS W/CODES article.
