I hope I am posting this in the correct place. My 2015 RZR 1000 XP started running rough then just wouldn’t start and gave a code of 520344 with a 17 under it. My local Polaris shop said it is either the O2 Sensor or the fuel pump. I changed the O2 Sensor but still wouldn’t run. I can smell gas so I know the fuel pump is working maybe not correcley but it is pumping gas. Pulled the plugs to find they were wet with gas cleaned and replaced and it started right up and ran for a second or 2 then died and wouldn’t start again. Any help would e greatley appreciated.
