Hello everyone I have a 08 ds450 here phone stock. I'm experiencing an issue it shut off on me the other day and now I cannot get it to start. My problem is my injector will only pulse once maybe twice every two or three key cycles. I have checked all relays replaced all sensors, ignition switch, relays, center harness, handlebar switch. I swapped ecms off of a parts quad I have and I'm still having the same issue can anyone give me any insight?
