2019 rzr 570 engine cutting off

[PF3]

Rzr has been sitting unused inside garage for about 18 months. Engine started and run about 15 min every 1 or 2 months.  Never any problem starting or running. This week took it out of town to ride for a day. Loaded, unloaded with no problems. After unloading went trailing. After about a 1/2 mile we went down a small kill and started up another hill and engine died. Restarted many times and died each time after only free seconds. Brought it home and started several times with same outcome.  Changed to fresh fuel and started it.  Lasted about 90 seconds (at idle) and died. So we started it several times and revved the engine up and it continued to run (while still revved up) each time until we dropped it back to idle and it died each time. HELP! Please.

Sounds like carb issues, i would have thought, like you, starting and running it would have kept that from happening, if you are running ethynol fuel it has a tendacy to form a jelly like substance in the carb from sitting, if thats the problem, fairly easy to clean up, if it hasnt rusted everything in there.

[Mech]

It sounds like it could be water in the fuel. If there's a way to drain the carb I'd do that, and check the flow to the carb is adequate..

The 2019 rzr 570 is efi so no carb involved. Need to check if the fuel pump is building pressure and go from there with the diagnoses.

[Mech]

Oh ok. Then yeah, check the fuel pressure.

I'd also put the timing light on it and make sure the spark wasn't failing before the engine stopped turning. If the spark fails the engine will do a turn or two before it stops, but if it's a fuel problem the spark will keep firing right down to near the engine stopping turning, or to below idle speed at least.

I would also try some fuel injector cleaner in the fuel, I use Berryman Chem Tool you can get it at Wal mart, i really like this stuff, it actually works.

[Mech]

Yeah that might be a good idea..  A bit of water absorbed into the fuel can make injectors sticky..

You figure it out?

Finally have some time to spend on my problem today.  Thanks for all of the feedback. Will let you know results.

[Gwbarm]

Glad to help, hope it turns out to be something simple.

[PF3]

Used Berryman as suggested. It solved the problem. Took Rzr out this week and ran it on trails for 2.5+ hours.  It ran.great without and problems.  Many thanks.

It’s good stuff, glad it worked for you.
