Solaris/syvecs runs Seq ignition and seq injection chap. None of that crap wasted spark here
If they are new injectors then i would suggest getting a battery and hook the injector straight up to that and see if it clicks as they have a habit of sticking if not used for ages. If it doesn't click using a battery then give it a tap on the bench. Usually does the trick.
If it works on the battery then try again and if it still doesn't work then i will talk you through how to use the output testing on the S6 which will come in handy for testing each injector with the engine not running.
