Engine Cranks But Will Not Start

  1. Check fuel tank contents and fuel gauge accuracy. Check for dirt, water or contamination in fuel.
  2. Check fuel lines and fittings for leaks. If no leaks are found, check fuel delivery system for proper pressure and volumes. Reset Inertia Fuel Shutoff (IFS) switch (if necessary).
  3. Check for damaged or corroded fuel injector wiring harness and connector. Ensure fuel injectors pulse when engine is cranked.
  4. Check ignition system for strong spark at spark plugs. If no spark exists or if spark is weak, proceed as follows:
    • On all EEC-V gasoline and CNG models, go to TEST JE in SELF-DIAGNOSTICS - EEC-V - CNG & GASOLINE article.
    • On Villager, go to TEST JA in SELF DIAGNOSTICS - VILLAGER article.
