No-Start Testing

Car Will Not Start.







Fault symptoms
Car will not start.

Conditions
The following conditions apply for this fault symptom:
- No diagnostic trouble codes in the car with the symptom description in question.
- There is petrol in the tank.
- Starter motor is in working order.

Diagnostic help
Most of the functions that can prevent the engine from being started are monitored by self diagnosis and therefore generate a diagnostic trouble code if they develop a fault. Consequently, this fault diagnosis concerns faults that can prevent the engine from being started but are not monitored.

First check that the fuel pump is in working order and delivers pressure. Then check the ignition discharge module and spark plugs.
