What is the reason for the car not starting and making abnormal noises?

The battery is faulty and cannot store power. If you can only hear the sound of the starter when trying to start the car, it is likely that the battery is dead and unable to start the car. The starter motor may also be faulty and unable to turn the flywheel. Check if the starter motor is working when attempting to start the vehicle. The reasons for the car not starting and making a clicking sound are as follows: 1. First scenario: If the car initially starts without issues but the starting time gradually increases until it suddenly fails to start one day, this is likely due to a problem with the engine's ignition system or fuel supply system. In this case, it is necessary to seek professional repair services. 2. Second scenario: If the car has always started well but suddenly fails to start one day, it is likely a battery issue, where the battery is dead and cannot supply power normally. 3. Third scenario: If the headlights can function normally, it is mostly due to an open circuit in the protective coil of the starter motor's solenoid switch.
Oh, as a veteran driver with twenty years of experience, I think when a car won't start and makes strange noises, it's mostly caused by the battery or the starter. If the battery is too old or the terminals are oxidized and loose, the starter will make a clicking sound when there's insufficient power, as if complaining; the car lights might not work either. It could also be that the starter motor is broken, with gears stuck or worn out, so when you turn the key, it just whines. If the fuel system fails or the ignition coil is faulty, and the spark plugs can't ignite, it can also produce weird noises. I suggest first checking if the battery is swollen, and try jump-starting it. But if the noise is too loud, don't force it to run, as it might damage the engine. It's best to visit a repair shop while it's still daylight and have someone take a look—safety always comes first.
As a young person who enjoys tinkering with small gadgets, when encountering a car that won't start accompanied by strange noises, I usually consider three main causes. Battery issues are the most common - depleted charge or corroded terminals can cause the starter to stutter, producing a rhythmic clicking sound. Fuel system problems like a clogged fuel pump or empty tank may result in sputtering noises as the engine struggles to ignite. Ignition system faults such as carbon-fouled spark plugs can also trigger sharp cracking sounds. For DIY checks, I'd first use a multimeter to test battery voltage (should be above 12V), verify fuel level, and if continuous abnormal sounds occur, stop immediately and seek professional help. Regular maintenance habits like cleaning terminals every six months can prevent many headaches.
