Hi everyone I just recently bought a 2004 arctic cat 900 efi mountain cat,runs really rich,no power, backfires,have 2 codes,1 is for water temp sensor(ordered),2and one is injector failure, so I pulled fuel rail with both injectors attached, got my buddy pull it over and only getting fuel from right injector,guy I bought it from said it needs a new ecu but I would like to dig little deeper before I spend the cash for another one,I checked continuity from injector plug to ecu test good,I read that the 2 blue wires from stator feed power to ecu for injectors,so would it be stator or ecu? Any help would be appreciated thank you.
