Went to check the code to see why check engine light is on and there is no power to jack. Any idea why?

    Were you using a simple code reader or a professional scan tool?

    Before you do anything else, check all your fuses. Some OBD ports are fused, often to the same circuit as a 12V power supply socket, or cigarette lighter socket if your truck has one.
