Engine Cranks But Will Not Start

  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 contaminated fuel injector wiring harness and connector. Ensure fuel injectors pulse when engine is cranked.
  4. Check ignition system for strong secondary current at spark plugs. If no spark exists or if spark is weak, go to step 1) of CIRCUIT TEST JA in the TESTS W/CODES article.
