What Causes Abnormal Noise and Failure to Start in the Starter?
2 Answers
Starter abnormal noise and failure to start are caused by battery power deficiency, motor malfunction, and excessive carbon buildup. The specific reasons and solutions for starter abnormal noise and failure to start are as follows: Specific reasons for starter abnormal noise and failure to start: Battery power deficiency: Insufficient voltage in the car battery. When the battery power is insufficient, it cannot drive the engine to reach the starting speed. The clicking sound during startup is due to the repeated engagement between the solenoid and the relay. Motor malfunction: Severe oxidation of the starting connection metal block in the motor control mechanism, resulting in poor starting contact. Excessive carbon buildup: Too much carbon buildup in the intake pipe, throttle valve, idle motor, and other parts can prevent the engine mixture from reaching the required air-fuel ratio, causing the vehicle to fail to start. This can also lead to the clicking sound of the solenoid and starter relay engaging. Solutions for starter abnormal noise and failure to start: Replace the battery; replace the severely worn motor starting gear and the connection metal block; clean the carbon buildup.
Last time my car did the same thing, the starter made a clicking noise but wouldn't start, it was so frustrating! I think the most common issue is a dead battery where the voltage is too low for the starter to turn properly, just buzzing weakly. It could also be that the starter's gears are broken or the solenoid is faulty, not engaging with the flywheel and making strange noises. Another possibility is poor wiring connections, with corroded terminals preventing current flow. I first tried jump-starting it, but when that didn't work, I took it to the repair shop. The mechanic checked and found the bearings inside the starter were seized, so they replaced it with a new one. Usually, keep an eye on the voltmeter to avoid letting the battery drain too often—it can save you a lot of trouble.
