What if Yazun can't start?

These maintenance items are routine maintenance items, and the failure to start may be related to cleaning the oil circuit and throttle. First, drive these components with a diagnostic computer to see if they can work normally. Secondly, the throttle body is initialized and re-matched, and then the test run is observed. There is also checking the spark plug. It is also possible that the spark plug was polluted when cleaning the fuel injector, so the vehicle could not start normally.
