Why does the car suddenly stall and fail to start?

[SiennaMarie]

The reasons why the car suddenly stalls and fails to start are: 1. The injector is dripping or the carbon canister solenoid valve is damaged, causing the mixture to be too rich; 2. Poor fuel quality leads to engine carbon deposits, which in turn causes the mixture to be too lean; 3. There is a fault in the engine ECU or power supply system; 4. The fuel pressure is too low. The method to start the car is: The ignition keyhole generally has four positions, namely LOCK, ACC, ON, and START. These four positions need to be turned step by step. Never turn directly from the LOCK position to the START position, because instant power-on will cause a great impact on the car's battery. The battery cannot instantly bear such a large burden and may "burn out" the vehicle's electrical system or electronic configuration. The key should be turned slowly to allow the electrical accessories on the vehicle to enter the state one by one, easing the battery's power supply pressure.
