What are the reasons for the car starter making noise but failing to start?

[StJustin]

When the car starter makes noise but fails to start, this phenomenon is generally attributed to a "broken cell" fault in the battery. The clicking sound indicates that the starter can engage, so first check if the battery is supplying power, and then verify if fuel is being delivered. Common reasons for a car failing to start: 1. Dead Battery: A dead battery is one of the most frequent causes of a car not starting. Apart from the battery's own quality and lifespan issues, improper usage by the owner often leads to a dead battery, such as forgetting to turn off headlights when parked or using too many external electrical devices. A dead battery typically manifests as the starter not working or turning over weakly when attempting to start the car. If the starter doesn't engage during ignition, it's almost certainly due to a dead battery. 2. Smart Key Battery Depletion: This issue only applies to cars with a push-button start feature. If pressing the start button yields no response and the smart key warning light on the dashboard remains lit, the smart key's battery is definitely depleted.
