Spark Check

WARNING: This page does not describe the selected car, but rather 15 other vehicles, including the 2000 Mercury Villager, 2000 Mercury Mountaineer, 2000 Lincoln Navigator, 2000 Ford Windstar, and 2000 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
  1. Perform self diagnostic QUICK TEST to check for ignition-related fault codes, and repair as necessary. See QUICK TEST in SELF DIAGNOSTICS - EEC-V (GASOLINE) article. If no fault codes are retrieved, check ignition system wiring harness connectors for corrosion and tight fit. See WIRING DIAGRAMS article. Clean or repair connectors as necessary.
  2. 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 TEST JD in SELF DIAGNOSTICS - EEC-V (GASOLINE) article.
