hi I’m Caylee and I own a 2005 Polaris sportsman 800 efi. awhile back I had noticed that the fuel gauge had gone bad because it would read full when it was not , it would be completely empty and still read fuel or half tank. a couple months after that I went riding and about 45 mins into my ride my fourwheeler had completely shutting down, acting as if it was out of gas. I pulled over and I noticed that the piece that connects from my airbox to my engine had only one bolt in it and was slightly hanging off . thinking that this was the problem I fixed the problem as soon as possible and thought that this was the solution to my problem. after that it I drove it again to begin back on my ride and about 30 mins it would do the same thing, start puttering. we let it sit for a little while and it would start up just fine . it kept doing that every so often. so I left it at my boyfriends house overnight and he cleaned out the radiator and it was very nasty so our other idea was that the clogged radiator was the possibility of the problem and that it wasn’t getting enough air which caused it to shut off. after that I had no problems with it and it drove fine. just today after letting it sit for about 2 weeks I put fresh new gas in it and pulled it around back to wash it off. I sprayed it down let it dry and started it back up and drove toward my garage and instead of it puttering and shutting off it just completely stopped. I turned the key and the efi is making a much more deeper sound than usual also this time it will not even catch fire even after letting it sit for over about an hour. idk what to do and I’m not sure if it’s the fuel pump or possibly the fuel injector. . but if anyone has had this problem before it would be so much help. the nearest Polaris store is about 1 hour away from me and I’d rather know the parts I need to get rather than buy the wrong ones ! thanks so much. I am opt to send videos of the start up sound too.
