    Car was low on gas one day and it turned off on me as I accelerated so I thought it ran out of gas. I put 5 gallons in and tried to turn on and now won’t even attempt to start, ran codes gave me a code u0100 “A” – cars computer not communicating with motor.

    is what it said. Changed starter and that didn’t do anything. Do I need to reset codes, replace motherboard computer, or is it a fuse or maybe sensor? Please help?
