What Causes Intermittent Car Starting Failure?

[DeTaylor]

Car intermittent starting failure reasons are as follows: Battery failure: The car engine makes a "click-click-click" sound, starts immediately upon ignition, but still fails to start after hearing the "click-click-click" sound, and the battery indicator light on the car dashboard is also on. This indicates a depleted battery. Spark plug blockage: The vehicle starts successfully, but there is obvious hesitation during startup. You should observe the engine's operation. If there is continuous shaking or intermittent shaking, it is likely caused by the spark plug. At this point, you can start with the spark plug to see if there are any hidden dangers, so as to replace it in time. Fuel pump pressure loss: After prolonged use, the fuel pump will inevitably experience internal wear, leading to insufficient fuel supply pressure and difficulty in ignition. In this case, replacing the fuel pump can solve the problem.
