What Causes a Car to Fail to Start with Abnormal Noises?

Such as carbon deposit-related faults in the fuel system, spark plugs, throttle body, etc. Below is relevant information about car engines: Engine Introduction: The car engine is the machine that provides power to the vehicle, serving as the heart of the car, influencing its power performance, fuel economy, and environmental friendliness. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems, among others. Engine Principle: The engine is the power source of a car. Most car engines are thermal power devices, commonly referred to as heat engines. Heat engines convert the thermal energy generated by fuel combustion into mechanical energy through changes in the state of the working medium.
Last time my car wouldn't start and made a 'clicking' sound, turns out it was a starter motor issue. As someone who's driven for over a decade, I've encountered this several times, especially in winter when the battery ages or terminal connections loosen. The starter gear can't engage the flywheel properly, causing this sound. I recommend first identifying the type of abnormal noise - if it's a scraping sound, it might be a broken belt or seized axle; if it's a whirring sound without power, perhaps low battery voltage is causing weak starting. You can check for battery terminal corrosion yourself and use a multimeter to test if voltage drops below 12V. Otherwise, have a mechanic repair the starter or replace components - don't force-start to avoid engine damage. Also, regular maintenance can prevent such issues. Remember unusual noises are often early warnings.
