Why won't the Jetta's dashboard light up and the engine start?
1 Answers
The reason why the Jetta's dashboard doesn't light up and the engine won't start is due to a malfunction in the ignition system or fuel supply system. The specific causes are as follows: Fuel supply malfunction: Clean the fuel filter screen, clean the filtering part of the system, and replace it if necessary. If it's the ignition system, check if the spark plugs have severe carbon buildup, if the ignition voltage is sufficient, and if the spark plugs have reached their usage cycle. It is recommended to replace the components if they have reached the cycle. Ignition malfunction: If the car won't start but the headlights turn on normally, this is mostly caused by a short circuit in the motor excitation coil. It is recommended to replace the motor magnetic switch.
