What is the reason for the continuous flashing of the P light when the car won't start?

It may be due to an electrical circuit or subsystem malfunction. Push-start method: If the car battery has exceeded its lifespan, special attention should be paid to regular battery maintenance, and replacement should be done promptly when necessary to avoid potential hazards. Push-starting is the most effective emergency starting method, but it should be used as a last resort and not frequently employed. This method can cause certain damage to the engine and clutch, and it should be particularly avoided for automatic transmission vehicles. Jump-start method: For jump-starting, first connect the positive terminal of the dead battery to the positive terminal of the rescue vehicle's battery. Then connect the negative terminal of the rescue vehicle's battery to a metal part (ground) in the engine compartment of the dead car. After connecting the jumper cables, start the rescue vehicle's engine and slightly increase its RPM. After about 5 minutes, emergency charging can be provided to the dead battery. Once charging is complete, remove the jumper cables in the reverse order of connection.
