I have a 2014 Sportsman 570 EFI with ~1000miles on it owns since new. I parked it in my outside garage this winter for storage and have been unable to get it running this spring upon returning back to it, there were no weird issues up to this, it was driven up to the exact spot that I am now trying to start it. It was stored with gas in it, so I started out by siphoning out all gas in the tank and filling the tank fully with fresh Super, then I unhooked the fuel rail and ran about 5 water bottles worth of fuel through it, so I am getting fuel at least as far as the rail. If the spark plug in pulled and set on the engine it receives spark, though I replaced the plug with an NGK plug anyways. The battery was testing at 12 volt, though the health was down to 30%, so it now has a new battery. The fuses and kill switch all appear to be normal and I've tried starting the machine in both Park and Neutral. I've also tried starting it with the gas cap off in case it may not be getting air. When you first turn on the key you can hear it prime the rail, though it will then just keep turning over at ~250rpm and not fire, if you prime the rail 3 or 4 times and try again there does not appear to be any change. I'm not great with EFI, so I've just tried all my initial thoughts, dealers and techs in the area are currently pushed out on appointments, so I would appreciate any thoughts that you may have on what to check. My next thought is to fully unhook the rail and injector and make sure that it is getting good spray and not clogged. Thanks!
