My freshly bought Lantra doesn’t start?Need help please

Hi I’m new here in the forum. My Hyundai Lantra doesn’t start any more. At the first stage of the ignition everything goes normal like ventilation, light, gasoline pump leaks through etc. But when the next turn there is no noise nothing it all goes out like light and radio and when turning back everything is on again.Need urgent help.Maybe that’s connected with the thing that you have to kick the clutch when starting that the part somehow doesn’t work I have no idea please help me
