    The reset switch is bad. Buy a new one at tk and replace it yourself

    you have a broken ground wire. Take a jumper cable from the engine to frame see if it start. If it does start then its a broken ground wire.

    Also to reset or clear code first turn off control box and then shut off engine switch then push reset button in then go out and turn on engine switch the turn on the control unit code should be gone

    The ground wire goes from the top of the engine head down the backside of motor to a junction stud at bottom backside of the unit. Also there another ground wire going to the alternator from this stud the fourth goes to the battery. I had the engine main wire ground break twice and the alternator once hope this help.
