What is the fault when BMW X5 fails to start?

[GiaMarie]

BMW X5's failure to start the engine may be caused by electrical circuit issues or battery problems. Below are relevant introductions about a car's failure to start: Check if the vehicle battery has power: If you can only hear the starter sound when trying to start the car, it is very likely due to a depleted battery preventing startup. In such cases, sometimes when the key is returned to its original position, the vehicle might start as the engine rotation slows down. Check if the vehicle ignition system is normal: Checking the ignition system usually requires two people to cooperate. Remove one of the ignition high-voltage wires from the engine, insert an old spark plug or other pen-shaped metal rod into the spark plug cap, and bring the spark plug body or metal rod close to the engine's metal part. Start the engine to observe if there is a high-voltage spark phenomenon. If not, check for ignition system issues. Check if there is fuel on the fuel gauge: Many new drivers, due to lack of experience, may forget to refuel. Without gasoline, the vehicle naturally cannot start. On uneven roads, fuel may concentrate on one side, sometimes preventing normal fuel supply and thus causing startup failure.
