Check the ignition coils and spark plugs for wear and tear, as faulty spark plugs can lead to starting difficulties.

Another essential step is to investigate the fuel system. A clogged fuel filter or a failing fuel pump can impede the flow of gasoline to the engine, resulting in starting issues. You can listen for the fuel pumps humming sound when turning the key to the "ON" position. If you dont hear anything, it may indicate a problem with the pump. Additionally, inspect the fuel lines for leaks or blockages that could disrupt fuel delivery.

Lastly, consider using an OBD-II scanner to check for any diagnostic trouble codes (DTCs) that may provide insight into underlying issues. These codes can help pinpoint problems related to the engine, sensors, or other critical systems. By following these steps, you can effectively diagnose starting issues in your 2017 Hyundai Sonata and take appropriate action to resolve them.
