EFI computer is not fireing them ran a test with a wide band o2 sensor in and no different with them hooked up or not
ah i see, you know, i don`t know if you have warranty but your owners manual might have some basic things to troubleshoot for that problem. With my charger i ditched the auxillarys and module and upsized my stock injectors and went with a custom tune. its just an option. it may cost the same as a new computer.(if thats the case) i would assume there must be some fuses or relays that could be checked in the unit. I guess you could start checking all the wiring to that baby, something could have come un-attached or shorted.
