Miscellaneous Component Or System Checks

Check the following:

• Check secondary ignition system. Go to TEST JB, step 1)  under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.
• Check fuel delivery system. Go to TEST HB, step 1)  (Natural Gas models), or go to TEST HC, step 1)  (all others) under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.
• Check exhaust system for restriction. Go to TEST HF, step 1)  under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.
• Check PCV system. Go to TEST HG, step 1)  under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.
• Check EVAP emission system for blockages (engine stalls) or leaks (excessive fuel odor). Service appropriate symptom under SYSTEM TESTS (EVAPORATIVE EMISSIONS) in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.
• Check air intake system. Go to TEST HU, step 1)  under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.
• Check starting system. See appropriate STARTERS article in STARTING & CHARGING SYSTEMS.
• Check Mass Airflow (MAF) sensor for contamination.
• Check high speed fuel pump secondary circuits (Lightning 5.4L SC models only). Go to TEST KA, step 70)  under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.
