What to Do When the Car Makes Abnormal Noises During Ignition but Fails to Start?
3 Answers
Car ignition with abnormal noises may be due to a dead battery, empty fuel tank, or incorrect gear position. Here is some relevant information about the car ignition system: Definition of the car ignition system: For a spark-ignition engine to operate normally, the ignition system must provide each spark plug with a sufficiently high-energy high-voltage current (approximately 15,000 to 30,000V) in the correct firing order, generating a strong enough spark to ignite the combustible mixture. Classification of car ignition systems: (1) Conventional ignition system: The working process of a mechanical ignition system involves the crankshaft driving the distributor shaft to rotate. The cam on the distributor shaft turns, causing the primary contacts of the ignition coil to open and close, thereby generating high voltage. (2) Electronic ignition system.
Last time my car made a strange noise when starting but wouldn't turn over. At first I thought it was a battery issue, and sure enough, the battery terminals were loose and corroded. After cleaning them, if it still doesn't work, try replacing the battery. If that doesn't help, the starter motor might be faulty. If the noise sounds like wheezing, it could indicate a clogged fuel system needing a filter replacement. A high-pitched squealing noise might mean the belt is worn and needs adjustment or replacement. Such abnormal noises usually signal electrical or mechanical component failure. Avoid repeated starting attempts as this can damage the vehicle. Immediately move the car to a safe location like the roadside or parking lot - never stop in the middle of the road. Then call for roadside assistance or contact a repair shop. Mechanics typically begin by testing battery voltage and starter current - prioritizing safety prevents bigger problems.
I remember one morning when my car suddenly made a buzzing noise but wouldn't start, which gave me a scare. It was probably due to the spark plugs not firing or the fuel pump failing to supply fuel. New drivers, don't panic. First, check if the dashboard lights are bright enough. If they're dim or flickering, it's definitely a sign of low battery power or poor connection at the terminals. Immediately ask a friend to help you jump-start the car using their vehicle. If the lights are normal but there's a loud abnormal noise, like a clicking or knocking sound, it might be that the gears in the starter are stuck and need replacement. Don't forget to check the fuel gauge to see if there's still fuel. If not, refuel promptly. If the problem persists, don't just wait in the car. Find a shady spot, get out, and contact your insurance company's roadside assistance service—it's quick and hassle-free.
