What are the reasons for the car making a clicking sound and failing to start?

The reason for the car making a clicking sound and failing to start is insufficient battery power, or it could be due to low battery voltage. If the car's headlights or other electrical devices were left on before the engine was turned off, or if there were too many external electrical appliances connected, the battery may be drained. It is important to follow proper vehicle usage practices in daily driving. Before turning off the engine, all electrical devices in the car should be switched off. Low voltage can also cause the car to fail to start and produce a clicking sound. The main reason for low battery voltage is prolonged use, leading to battery aging and reduced charge storage capacity. In such cases, it is recommended that the owner replace the battery with a new one.
That rattling noise is really annoying, and it gave me a headache last time I encountered it. The main reason is usually a dead battery, which is most common, especially in cold weather. When the battery is dead and the voltage is too low, the starter motor can't turn over. Additionally, it could be that the starter motor itself is stuck or the gears are worn out, causing that sound. Or, if the wiring contacts are rusty or loose, the current can't flow smoothly, leading to the rattling. I've also heard of fuel pump issues, like a clogged filter, where there's no fuel pressure to ignite. In short, quickly find a friend to help jump-start the car. If that doesn't work, you'll need to tow it to a repair shop to check the battery and fuel system. Don't wait until you're stranded on the road—it'll be even more troublesome.
