    Try starting the car in neutral or try putting the key in on position for 5 full minute without starting to "reset".  

    I would disconnect the main battery for a few minutes and reconnect and see what happens. You should do this because you need to remove the dead battery from the circuit by disconnecting its negative lead and additional drain of dead cells in that battery could cause voltage to drop so low during cranking that it could damage the vehicle's electronics.

    But don't forget also crankshaft position sensor will cause the same symptom
