First I would check the battery voltage after the car is parked. It may hint to a parasitic current draw. Hence the reason why you can't start the car.

What troubleshooting have you done so far? Do you have any codes?

baterry was at 12.3 V when is parked. My options turn odf battery issue because first time doesnt start, pull out key and back do same operation to turn on and car turn on from second chance. I thing problem was at key ignition, something ELZ EIS i dont know i found some people who repaired. Last time i turn on diagnostic for other problem on car and thay found me only 1 issue, issue of sensor of temperature at exehaust system ECU E8 code P0471
