Is car over heat last time to H level and shut off of its own, then show to proper mechanic as u must have fried many things.

If last time was fine and all of sudden when u start the cold car showing this H means, water temp sending sensor is bad and showing wrong reading in turn blocking the car to start. Change that 50-60 aed fix it will be ok.
