If no fault codes are retrieved, check ignition system wiring harness for damage or loose connectors. See WIRING DIAGRAMS article. Clean or repair connectors as necessary. - If wiring and connectors are okay, use Neon Bulb Spark Tester (D8IP-6666-A) to check for spark at each spark plug wire while cranking engine. If spark is strong and consistent at each spark plug (one spark per crankshaft revolution), ignition system is okay. If spark is not present, go to CIRCUIT TEST A in TESTS W/CODES article.
