HI All, I have a 2008 500 HO EFI. store with little to no fuel for 3 years. 40 hours, 170 miles. when parked, ran like a top. fast forward 2023 Dec, new battery, full of fresh oil, crank no start. I cannot hear the fuel pump prime like it should. Also will not start on Carb Cleaner direct into the intake. IT IS Efi I was using the carb cleaner to test for spark. I also tried new Fuel/Ignition relay (2 micro relays under the headlight) and no help. where do I start? How can I get codes? thanks all!

 

I don't know Polaris machines at all, but on any EFI bike I know of, if it faults electronically, the engine management light comes on, if it doesn't, you won't get fault codes coming up even if you do find out how to do it. Take the plug out, refit the HT lead and see if you are getting a spark. However, if you are not getting the sound of the pump running, my guess would be the pump seized. If you are getting a spark, check if the pump is getting power when you first switch ignition on, if it is, then it will be a seized pump.
