Hello! I am somewhat new to this world and to this forum so please excuse my ignorance on the matter. I sure could use some help here and some advice. I bought a 2007 Polaris Sportsman 500 H.O. X2 EFI last year. Only has a few hundred miles on it. It ran perfectly this past year then suddenly problems started a few months ago… When you go to turn it on, you turn the key once and the odometer display doesn’t turn on at all and all you hear is a humming sound coming from the fuel pump and click sounds coming from the EFI on the carburetor. This just continues on and on unless I turn the key off. However, “sometimes” if I turn the key and wait a few minutes the display will flicker on briefly and then flicker back off. When it flickers on the humming stops and the EFI stops clicking, but when the display goes off the humming starts again and the clicks start again. Now other times the screen will flicker a few times and then it will stay on, so then I turn the key and the ATV fires up no problem and I can go a ride it for hours with no issues. Then I can turn it off and back on 11 times in a row with no issues, then suddenly at random it will do the same thing again, screen flickers and won’t come on and the fuel pump hums and EFI clicks. A few times this happened while in mid ride with the ATV on and the display shut off and as did the ATV. I can NOT find any consistency with this issue. Sometimes it takes me 20 minutes until the display will flicker and finally stay on and I can start the ATV and ride, but then it might shut off a dozen times while I ride it doing the same issue, or I can get the ATV started in 1 minute and not have it shut off at all… I am totally lost. I put a brand new battery in, tripled checked my positive and ground cables were secure and had no corrosion. I have no idea what the issue could be since it is so random. I took a video of the issue, but I’m not sure if I can upload here. Please any help would be great! Thank you in advance.
