You can start test by key on. But you’ll want a running test as well. Odds are if it won’t start it’ll be low pressure or contaminants in fuel like water
I have a 2008 polaris ranger it won’t start and the only way it will start if i press the gas pedal all the way in but wont stay idling if i let go of the pedal ?
take some brake cleaner and clean the throttle body and the little sensor inside a cage and it’ll run perfectly, i had the same problems until i found a video saying to do that
