Why won't the car start when the battery has power?

[CarsonLynn]

There are several reasons why a car with a charged battery won't start: Incorrect gear position: If the gear is in D or R position, the engine won't start. It will only start when in P or N position. Out of fuel: Apart from a dead battery, lack of fuel can also prevent the engine from starting. This usually happens when the engine is left running while parked, eventually draining both fuel and battery. Faulty fuel pump: If the starter motor operates normally during ignition but the engine doesn't start, you should check the fuel management system.
