What are the reasons why the Baojun 510 battery has power but cannot start?

[McHayden]

Reasons why the Baojun 510 battery has power but cannot start: Battery depletion: Having power doesn't mean the battery voltage is sufficient to start the engine. Prolonged use can easily lead to battery aging, and insufficient voltage to activate the starter will prevent engine ignition. Therefore, when unable to start, it's necessary to determine whether it's due to insufficient battery voltage, starter failure, or other reasons. Other reasons: The gear being in D position prevents ignition, which is the car's automatic protection mechanism to prevent sudden movement after ignition; damage to the fuel pump causing inability to pump fuel; severe carbon buildup in the throttle leading to insufficient throttle opening, preventing combustible mixture from entering the cylinder for combustion and resulting in failure to start.
