What Causes the Clicking Sound and Failure to Start When Igniting a Car?
1 Answers
The reasons for the clicking sound and failure to start when igniting a car are as follows: 1. Starter motor failure: Unable to drive the flywheel to rotate. Check if the starter motor is working when starting the vehicle. 2. Battery failure: Unable to store power. If you only hear the sound of the starter when starting the car, it is likely due to a depleted battery preventing startup. 3. Vehicle fuel supply system failure: Disconnect the oil pipe joint on the engine, turn the ignition switch to the position where the dashboard lights come on (without the starter operating), and observe if there is any oil flow. If oil flows, the fuel supply system is fine; if not, further inspection is needed. 4. Vehicle ignition system failure: Remove one of the ignition high-voltage wires from the engine, insert an old spark plug or other pen-shaped metal rod into the spark plug cap, and place the spark plug body or metal rod close to the engine's metal part. Start the engine and observe if there is any high-voltage sparking. If not, check for ignition system issues.
