What Causes the Engine to Fail to Start with Abnormal Noises?
2 Answers
Engine failing to start with abnormal noises can be caused by a dead battery, damaged spark plugs, circuit faults, or a faulty starter motor. The specific reasons are as follows: Dead Battery: A dead battery does not mean the battery is completely out of power, but rather that the voltage is insufficient to start the car. In this case, you need to jump-start the car or replace the battery. Damaged Spark Plugs: Damaged spark plugs in the engine are one of the reasons why a car fails to start, as the spark plugs ignite the gasoline in the cylinders to get the engine running. Distributor Circuit Fault: The main circuit for ignition is the distributor. If the distributor is damaged, it may also prevent the engine from starting. Faulty Starter Motor: The starter motor is responsible for turning the engine during ignition. If the starter motor is damaged, the engine will not start.
Once my car had the same issue, the engine wouldn't start at all and made a squeaking sound. I was quite anxious at the time, but later found out the problem might be caused by insufficient battery power or poor contact. If the battery is old or the terminals are corroded, it can affect the starter motor's operation, and when the starter motor can't turn, it makes a clicking sound. This is especially common in winter because low temperatures reduce battery efficiency. I first tried cleaning the terminals and jump-starting the car with another vehicle, and it worked. It could also be a generator failure; if it doesn't charge, the battery will quickly run out of power. If the starter motor is stuck or the belt is loose, it can also produce noise. I recommend first checking if the battery connections are clean and tight, and if necessary, ask someone to help jump-start it. If it still doesn't work, it might be due to internal component wear needing repair or replacement. Regular maintenance is crucial to avoid travel disruptions.
