Look at each side of the injectors that show ohm ratings and the wiring colors and where they go.Red/black leads to the splice 1 and 2. Not a clear copy but you should be able to see. https://www.manualslib.com/manual/94...age=301#manual

 

Thank you. I missed that on the diagram.

I switched the injectors around to see if it killed the other cylinder, and it indeed did, so I know its not anything between the ECU and the plug. I then took my tester and stuck the two ends on the two pegs in the injector plug and it read 15.0, so I'm guessing its not a wiring problem.

I then put the injectors back in the rail and turned it over while pointing them at a piece of cardboard. The good injector had a nice mist, the bad injector just dribbled fuel out a few drips at a time.

Couple questions: I ordered an injector rebuild kit because I needed new o-rings an it came with new micro filters so I replaced them..If I accidentally got something down in there while changing them, would that cause something like this? Or does this basically mean the injector is junk and needs to be replaced?

Thank you again for all your help OPT!

 

Possible injector screen has trash in it. You can try low air pressure through the screen to see it that solves it.If not,then you may need a new injector.Polaris RZR Ranger Sportsman 700 800 EFI Genuine Bosch Fuel Injector - 1202863 | eBay
