VCM, not ECM. Side panel. 2nd long one from left facing it. Hold out for 30 seconds to ensure discharge .I would try pulling the main ecm fuse for few minutes. See if maybe it’s just a weird glitch. Of course check your battery terminals. If that delivers no joy then it’s probably a bad throttle position sensor.
Replacing the throttle unit and relay. Polaris covering the parts, I get the labor cost. Bikes warranty was up in July. So it is what it is. Between hard or not starting when it's cold, to having to already have the starter and battery replaced (warranty), really feeling I'm not suited for this bike.What is the status Ron?
