Why does the car fail to start and make abnormal noises?

[SanAlexandra]

Car starting failure accompanied by abnormal noises can be caused by insufficient battery power, faulty spark plugs or ignition coils, engine motor idling, or poor fuel quality. Insufficient battery power: Check the battery's power status and charge it in time, as insufficient power can reduce its service life. Faulty spark plugs or ignition coils: Inspect the condition of the spark plugs and ignition coils, and replace them if necessary. Engine motor idling: Check the working condition of the engine and transmission, and inspect whether the flywheel ring gear is slipping. Poor fuel quality: Check the fuel quality and use guaranteed-quality gasoline to minimize damage.
