Engine Ignition - V8 5.0L Petrol/V8 S/C 5.0L Petrol - Engine Ignition
Diagnosis and Testing
Principles of Operation
For a detailed description of the engine ignition system and operation, refer to the relevant Description and Operation section
of the workshop manual. REFER to: (303-07B Engine Ignition - V8 5.0L Petrol/V8 S/C 5.0L Petrol)
Engine Ignition (Description and Operation), Engine Ignition (Description and Operation), Engine Ignition (Description and Operation).
Inspection and Verification
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle.
NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical and electrical damage.
Visual Inspection
Mechanical Electrical
Engine oil level
Cooling system coolant level
Fuel level
Fuel contamination/grade/quality
Exhaust gas recirculation (EGR) valves
Fuses
Wiring harness

Ignition coils
Sensor(s)
Engine Control Module (ECM)
Transmission Control Module (TCM)
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, verify the symptom and refer to the Symptom Chart, alternatively check for
Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.
