Any tips on diagnostic steps for a 2015 Rubicon? Was running fine then just quit. It has spark, runs on carb spray. I can hear fuel pump running but don't have a way to check pressure. I know it isn't getting fuel. Has a full tank of gas. Leaning towards an injector. Anyone have any suggestions or specs or a manual to share. Thanks in advance!

maybe drain fuel and try fresh fuel
ethanol fuel can go bad fast
all the more so if your a water guy and got water in the fuel

the fact it runs on starting fluid, says, it could be fuel related to me!

Thanks for your reply. I did think of that but the way I was told it quit suddenly made me think it was probably a component failure. He did tell me he just filled the tank with fresh premium gas right before it happened so I will take a fuel sample and see. I work on outboard motors and see water in the fuel quite often but usually they still run just really poorly. But the way ATV tanks are built if there was water in the can he just poured in. Once it separates it would concentrate at the bottom of the tank and there could be 100% water in the line now. I will let you know what I find out Thanks!

water can for sure shut things down FAST
and again, don;'t know how atv was used, but folks these days sure sem think many ATV are more boat like than they really are

so water can get into tanks in many ways!

and even poor fuel can cause NO running

also, a dirty fuel tank can pass things into places that clog fuel flow too,

some time dirt can come in from a fuel station, or a dirty fuel can, or, as said, from folks riding atv's in deep water and water getting in tank and carrying dirt with it
