Retrieve the trouble codes and let us know what they are. It could be more than just one code. If it is the cam position sensor, it can cause non starting.

If it is P0104, that can cause non starting as it is related to the Mass Air Flow sensor.

My problem was a relay in control box were fuses are stored i believe it was a icc relay.

A bad relay can cause intermittent non starting and stalling as circuits can break intermittently when resistance increases due to heat. It is never easy to diagnose such faults and that is the reason you need to diagnose when problem occurred and find out what is missing.
