Hi, power pins and K-Line must be connected to "A" connector. Only bootpin is at "B" connector. Tested and 100% works.

I conect power and k-line 100% on the right pins because I tested incoming power on the wires only boot pin I tryed on the both conector but not work,maybe ecu is fault the car can,t start?

Try this way:
Mount ECU in the car and connect only "A" connector (for power supply and K-Line). At "B" connector connect pin 20 to GND. Turn ignition ON. Don't disconnect bootpin. Now ECU should be in boot mode. You should be able to reading and programming ECU. After all just turn ignition OFF and disconnect bootpin from GND.

BTW. Did You try to connect any diagnostic tool to check for ECU faults or just for communication possibility?

Olso tryed this way but the same,eror :boot mode inactive,when I conect diagnose I can normaly read faults.I want to disable immo because there was fault U 1600 with code but it has 2 keys and the same with both.And also 2 faults with can bus but wires is ok.This faults is can bus with Bcu(no faults inside) and servo but servo is ok too?
