The injectors have a fuse from what I recall, not sure what # it is on your car.

This has DAS X antitheft. Chip in key , RFID antenna around the ignition lock , small black box behind the instrument cluster ( 210 820 32 26 , just follow the RFID antenna wire )

The DAS box is locked to the engine computer so if you sub parts, you need the key / DAS and engine computer all to match. I know the injectors are shut off if DAS does not see the proper key, not sure if the ignition shuts off too. From what I recall there will be at least a start stall if DAS does not release.
