VISUAL INSPECTION
Visually inspect all electrical wiring, looking for chafed, stretched, cut or pinched wiring. Ensure electrical connectors fit tightly and are not corroded. Ensure vacuum hoses are properly routed and are not pinched or cut. Inspect air induction system for possible vacuum or pressure leaks.
Fault Symptoms
Car will not start.
Diagnostic Help
Most functions that can stop the engine from starting are monitored by self-diagnosis and therefore generate diagnostic trouble codes if they malfunction. This fault diagnosis therefore applies to faults that are not monitored but can prevent the engine from starting.
Make sure the fuel pump is in working order and delivering pressure first. Then, check the crankshaft position sensor, ignition discharge module and spark plugs.
Functions in the diagnostic tool related to the fault
- Activate the fuel pump relay.
- Activating ignition triggers.
