I have a 2016 Ranger 570 crew EFI. It has been rode very frequently and the other day I got on it, cranked it up to which it cranked and ran while I when to grab something and when I got back it had turn off. I tried restarting and it turns over but will not crank and is almost full of gas. I disconnected the fuel line coming out of the fuel pump, turned the key and gas is coming out. I reconnected and disconnected the line where is goes in at the rear, turned key and gas is coming out there as well. I removed the spark plug, tested and I am getting fire. I did go ahead and change the spark plug just to see and still same problem. I checked the fuse box under rear seat and all of the fuses look good. I'm stumped. Does anyone have any ideas or experienced the same problem? Thanks!

I will have to get a gauge. But, when I took the fuel line loose from connection in both places it shoots out a good stream, not just trickling out. Even if pressure is low, wouldn't it try to start? Its not even trying to start. Thanks!

It needs to have real pressure, it needs it to spray the fuel... Normal running pressure is close to 50psi, under 25psi they won't run, So worth checking it's correct.

I've also had the ht leads corrode where it plugs into the coil on the 570s, but if you have a spark I'd expect that to be ok.

What ever came of this? I am having the same problem except I didn't have hardly any fuel come out of the line...

I'm not getting any voltage reading from the red wire on the fuel pump plug--not sure what that means...I'm not very knowledgeable with mechanics, but trying to learn and prefer to be self-sufficient...any help is greatly appreciated! Mine is a 2014 Ranger 570 efi Crew

I'm having the same problem with my 2015 Ranger 570 EFI Crew. Fuel pressure 60 psi (holds), strong spark, good battery, fluid levels good, wrench and hour glass on instrumentation (needs service, shouldn't keep it from cranking). Turns over, but will not crank. Starter fluid will make if fire, but not crank. Any advice is appreciated.

Hey! just wondering if you ever figured this one out! Looks like a mystery bug on these machines, did all the checks and can't get mine to start either. same exact symptoms. Anyone with any updates would be greatly appreciated. Thanks!

I fixed mine by replacing the fuel pump.

I did a fuel pressure test and it seemed good, just seeing the pressure by priming the pump.

but then as someone recommended, I put the pressure gauge in series, started it up, and watched the pressure fall.



for sh**s and giggles, prime the fuel pump about 3 times with the key before starting, see if it starts up.

if it does, it will die shortly after, and this means its your fuel pump. or fuel regulator if you want to just replace that.

feel free to read my post here

Anyone have the OEM part number for the entire fuel pump assembly on the Polaris Ranger 570 efi machine, or a secondary manufacturer’s part number?

That’s a 2014 Polaris Ranger😎
There are two (2) OEM fuel pump assembly numbers: #2208613 and #2204945 (apparently this latter number is the old number). My 2014 570 Ranger EFI was working fine last year and while driving out to one of my pastures, when I git out to open a gate, the engine just stopped. Tried to re-start it - no luck. Towed it back to the barn, ran through the usual suspected causes (fuses, connections, low or bad fuel, and so on, without any luck. Tried a new fuel relay fuse - no luck. So, because we were getting into winter weather, for the next several months I just used my pickup truck to check the cattle. Then in March I started looking at the Ranger’s “problem” again. Bit the dust and got a new fuel pump assembly. Got all the old fuel out, thoroughly wiped down and cleaned the fuel tank, installed a new fuel pump assembly, added fresh fuel, and VOILA! The Ranger started up like nothing had ever happened. Still running well as of May 2021.
