What are the reasons why the BYD Surui cannot start?

[Jesse]

There are many reasons why the Surui cannot start, and it is recommended to troubleshoot the issue promptly. Below is a detailed analysis of the specific reasons why a car may fail to start: 1. Battery depletion: When the voltage during startup is lower than the minimum working voltage required by the computer, the engine computer will not function, preventing the car from starting. In this case, the battery should be recharged or replaced. 2. Spark plug failure: Spark plugs are prone to damage, and issues such as short circuits in the high-voltage lines can prevent the spark plugs from igniting. Additionally, low-quality spark plugs can also cause startup failures. It is recommended to replace the spark plugs in such cases. 3. Starting circuit malfunction: If there is only a slight 'click' sound during startup with no further response, this is usually caused by a stuck starter relay. Pressing the tail of the electromagnet to force it forward can reconnect the starting circuit, allowing the engine to start. 4. Use of low-quality engine oil: During cold starts, factors such as cylinder pressure, engine speed, and temperature can make it difficult to ignite low-quality engine oil, preventing the car from starting. It is recommended to use the manufacturer-recommended engine oil or a higher-quality full synthetic oil.
