Starter Makes Abnormal Noise and Fails to Start When Turning the Key?
1 Answers
Abnormal noise when turning the key and failure to start are mostly caused by starter issues. Solutions for the failure to start when turning the key are as follows: 1. Use a household multimeter to measure whether the car battery voltage reaches 12V or above. If the measured voltage is less than 10V, the vehicle cannot be started. In this case, the battery must be charged, or you can try jump-starting the vehicle using another car's battery. However, it is important to note that starting attempts should not be too frequent. If the vehicle fails to start after 2-3 attempts, you must wait about 5 minutes before trying again to avoid severely draining the external battery. 2. If the battery is normal, use a multimeter to check whether there is power supply to the starter. If there is no power, it indicates a power supply issue in the starting system. You need to check for loose, broken, or aged starter wiring. After repairing, try turning the key to start again. 3. If there is power to the starter but it still doesn't work, it is likely that the starter relay is faulty. Check whether the starter relay is burned out (usually located in the engine compartment fuse box; refer to the instructions on the fuse box). A burned-out starter relay can still produce a clicking sound, but its power transmission capability is reduced, making it difficult to start the vehicle. 4. If the starting system is normal, then check the ignition system. It is possible that the spark plug ignition end is dirty with oil. Remove and clean each spark plug one by one, and it is best to reinstall them in order to avoid incorrect installation leading to poor ignition symptoms.
