Start problems – no spark Kia Rio Cool Navigator

Hello dear ones! My Kia Rio Cool Navigator has been having trouble since the month 2010. It had started that he could not be started sporadically – after a short wait it went again. Until the day when nothing went and the engine went out during the ride and could not be started. Was then in the kia workshop where on suspicion the control unit of the immobilizer was changed, took him out of the workshop and stood 5min again After a week there can be they didn’t understand the mistake, so I picked him up and stood there for 5min again – engine went out during the ride and didn’t let it start. He didn’t give a spark No workshop can “trigger” the problem and auvh after some test drives didn’t hit the problem Now I remembered, I have my daughter’s child seat standing on the passenger seat…with my rides she was always there, with the test drives of course not. sous, my question therefore – runs in the footroom of the passenger side anything that could be “pushed”? ??? Thank you in advance Dear greetings
