Symptom Diagnosis

Symptom checks cannot be used properly unless the problem occurs while the vehicle is being tested. To reduce diagnostic time, ensure steps in BASIC DIAGNOSTIC PROCEDURES and appropriate SELF-DIAGNOSTICS articles were performed before diagnosing a symptom. Recommended system and component checks may not apply to all vehicles. Troubleshoot symptom probable causes in order listed under symptom checks. Symptoms available for diagnosis include the following:

• Engine Will Not Start 
• Hard To Start 
• Cold Fast Idle Too Low 
• Cold Fast Idle Too High 
• Idle Speed Fluctuates 
• Warm Idle Speed Below Specification 
• Warm Idle Speed Above Specification 
• Lack Of Power 
• Engine Stalls 
• Difficult To Refuel 
• Fuel Overflows During Refueling
