Weizi doesn't ignite or inject oil.

Reasons for VIZ non-ignition and non-fuel injection:

1. Nozzle blockage: Nozzle blockage means that impurities in fuel block the nozzle channel. At a certain temperature, the unstable components in gasoline will react chemically to form a gelatinous viscous substance, which will block the needle valve and valve hole of the injector, thus affecting the performance of the engine, leading to the decline of power and abnormal operation of the engine. Sometimes it can catch fire, and sometimes it can't.

2. Throttle has carbon deposit: The carbon deposit in the engine has a great influence on the engine, which will reduce the engine power and make the power output uneven. It will also increase fuel consumption, and it will also make it difficult to start a cold start, strike a fire and get a taxi.

3. There is something wrong with the fuel system: the oil pump is damaged and the oil circuit is blocked, which will lead to insufficient fuel supply. Without enough fuel to participate in combustion, the concentration of mixed gas will be too low, which will make the spark plug not easy to ignite and the car not easy to catch fire.
