16.4.3.2 Fault phenomenon - unable to start
a) Make the ignition switch at "ON" file to check whether the engine fault light is on
If not on:
Check the fuse and earth wire
Check whether the ECU's patch plug is securely connected
Diagnostic apparatus may also be used to execute agency check function to check
whether the light and line are normal
Check and repair the bulb and its line
Use another ECU to determine
If on:
Connect the diagnostic equipment to the system diagnostic socket
b) Whether the diagnostic apparatus can connect and communicate with the system
If not:
Check the fuse and earth wire
Check whether the ECU's patch plug is securely connected
Check whether the diagnostic apparatus in another normal vehicle is working properly
Use another ECU to determine
If so:
According to the fault indicated by the diagnostic apparatus for troubleshooting.
c) Check the ignition system failure - whether the spark plug is normal ignition
If not:
Check whether the high-voltage lines and spark plug patch firmly or are damaged
Use another ignition coil assembly to judge
Use another ECU to determine
If so:
Check whether the high-voltage lines is properly connected to the ignition coil and spark
plug
d) Check the fuel supply system failure
Whether the fuel pump is working - working of pump can be hears near the tank when starting the engine
If not:
Check whether the fuel pump relay is working properly
Check whether the crankshaft position sensor is connected and work is normal.
Use another ECU to determine
Check the fuel pump lines
If so:
1) Whether the supply pressure is greater than 220Kpa
2) Pressure is
insufficient:
3) Pressure is
normal:
Check the fuel tank if there is sufficient oil
Check the fuel filter whether it should be replaced (Note: The EFI
