Make sure that the clearance between rotor and rotation speed sensor is 0.

12. Spark plug
Spark plug type: CPR8EA, standard valve of contact clearance for spark plug is 0.85~0.95mm.
4.2.2 Removal, Maintenance and Installation of EFI
1. Basic principle of fault diagnosis
1
)
Fault message record
ECU detects the sensors, relevant circuits, fault indicating light, battery voltage and even ECU itself constantly. And it checks the reliability of output signals,
internal signals from the sensor. Once the fault is found, ECU will record the fault message at the memorizer of chips.

)
Fault type: short circuit, broken circuit, lost of signal
3
)
Failure warning: There’s fault indicating light on the meter, so almost all sensors on the EFI system can be detected. If fault is detected, the fault light will be
lightened to warn until the fault is handled.

)
When open the key switch but didn’t start the engine, the fault light will be lighten for 2~3 seconds. If there’s no fault, the fault light will be extinguished.
Otherwise, the fault light will glitter according to the codes (see below table):
