I have a 2014 polaris sportsman 570, and the fuel pump recently stopped working. I replaced the pump, and spark plug, and put everything back together. Took for a ride, and it started to spit and sputter when I accelerated, and smelled rich fuel smell. So i ordered a fuel pressure regulator, and put it back to gather, and still doing the same thing. I now ordered a fuel injector which I haven't recieved yet. If I keep it below 3000rpms it doesn't do it what can be the problem.

Its on the throttle body and has to be accurately calibrated to the correct voltage output. Unless you have the knowledge, special tools and the correct specs for your particular machine it would have to go to a shop that has those things or to a Polaris dealership.
