What Causes a Car to Make a 'Tut-Tut-Tut' Sound and Fail to Start?
1 Answers
Common reasons why a car fails to start include: 1. Fuel pump issue—you can diagnose this by observing the response after turning on the ignition. If you hear the fuel pump running, it's not the problem. Conversely, no sound indicates a faulty fuel pump that needs immediate replacement. 2. Spark plug issue—problems like excessive spark plug gap, reaching the end of its service life, or carbon buildup can make the car hard to start and produce abnormal noises, requiring timely replacement. 3. Fuel injector issue—clogged injectors leading to poor atomization or carbon buildup are also related. Try cleaning the injectors first; if that doesn’t work, replacement is necessary. 4. Throttle body issue—a malfunctioning throttle body can also cause starting difficulties and abnormal noises. Cleaning the throttle body is recommended, as regular maintenance is required after driving a certain mileage.
