What if the car doesn't catch fire?

1. There is no response when the vehicle is powered on, and the instrument light is dim: under normal circumstances, if the battery light is on before starting the instrument panel self-inspection, it is obvious that the brightness of the instrument panel is not normal, and it can be judged that the battery is dead or has reached its service life. Sometimes the instrument doesn't display, but when you start the car, you can obviously feel that the engine is running very slowly, which is also a precursor to battery loss. At this time, the best solution is to change the battery in time, and don't wait until it is completely dead.

2. The battery does not lose power, and the engine starts normally: after the ignition is pressed, the engine sounds normally, and there is no obvious dimming of the screen or the indicator light in the car during work, indicating that there is nothing wrong with the battery and the engine. If there is no fire at this time, there may be something wrong with the high-pressure oil pump and the driving computer, or the engine has no oil supply, so this situation can only be called trailer rescue.
