I put the new relay in my 2008 sportsman 500 ho EFI touring and she still didn't make an offer to roll over. I unbolted the relay harness to find one of the wires had become disconnected from the harness. I managed to get it back and the bike started to roll over but still not hearing the fuel pump pick up the fuel. The fuel pump make a small humming noise, not the regular sound when you turn the key on and makes the clicking noise when you shut it off. I removed the fuel line from the top of the fuel pump and fuel came out of the line. I took the spark plug out and had no spark. the spark plug is good because i check it in another ATV. Any help would be greatly appreciated!

 

On no spark condition on efi machines could be a number of things to check out. If you don't have a manual here's one for 5 bucks that has a trouble shooting guide for ignition and fuel pump issues and checks rather just throwing parts at it. 2008 Polaris Sportsman 500 EFI Service Manual PDF Download
