EDIS (DISTRIBUTORLESS)

NOTE: Continental, Crown Victoria, Grand Marquis, Mustang and Town Car (4.6L), Sable and Taurus (3.0L 4V), and LS use Coil On Plug (COP). COP faults should set a DTC. For additional testing, see TEST JF in SELF-DIAGNOSTICS - EEC-V - CNG & GASOLINE article.

  1. Spark Check

    Perform self diagnostic QUICK TEST to check for ignition-related fault codes, and repair as necessary. See QUICK TEST in SELF-DIAGNOSTICS - EEC-V - CNG & GASOLINE article. 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.
  2. If wiring and connectors are okay, use Neon Bulb Spark Tester (D8IP-6666-A ) to check for spark at each spark plug 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, see TEST A in SELF-DIAGNOSTICS - EEC-V - CNG & GASOLINE article.
