This helped me out big time, my sportsman 450 was doing the exact same thing and we were chasing our tails trying to figure it out. The fuel pump seemed to b working just like yours so we suspected the injector. After watching this video and reading the comments we bought a fuel pump from the dealer and installed it. It fired up right away and ran like new!
My 450 polaris did same thing. I cleaned my fuel pump out took it apart , and it ran fine. Till kids ran it out of gas. Acted up again so I put new fuel pump in from ebay, worked great now. No cutting out or stalling.
You only buy a polaris once then you get a honda or yamaha. I bought a pair of 570 sportsman 2016 the batteries were too small and in the wrong place the engine heat blows at your legs. The heat shields for the exhaust are not adequate it melts the tail light wires. Just not well engineered at all. Idles too low and stalls all the time. The gear box is like mush. Can’t tell by feel what gear you are in. The good thing is they will be my last polaris. Going back to yamaha as soon as I can.
I checked my fuel. New spark plug, I cleaned injector, I swapped out parts. Still ran bad. Took my polaris ranger fuel pump out and put it in my 450 sportsman and ran great. So I bought a new pump off ebay. No problems anymore.
Have 16 450 EFI HO Polaris. Never had any issues before. Now won’t stay idle for long. And will lose power when you try driving. I’ve changed the plug, clean air filter. Even changed out the old gas with New. Maybe you can help me with my problem or anyone else
i found the negative wire on the fuel pump on my 2017 caused the same issue......the wire was loose recripmed it and put pump back in ran perfect (except for the blown regulator)
@Noe & Ashley Cabriales same here changed fuel pump and still wanting to stall . Did you get yours fixed if so id greatly appreciate figuring out what the problem was

Fuel pump pressure is low. I think it takes 50 lbs. anything less causes your problem.

Did u ever find out what the issue was

It is your fuel pump it will pump but not enough pressure
Hey man do you remember having any check engine codes?
It’s the sensor or the fuel inyector
Try changing the battery mine did the same thing changed battery and worked great
Did the battery actually fixed your issue? Mine is doing the same thing put a new fuel pump and still doing it
Mines doing the same thing and I replaced the battery
Have you resolved this yet? Please share your progress.
It was the fuel pump, while it did push a little fuel the psi was not high enough to run the engine

Fuel pump yo. Yes it is the fuel pump. I just fixed mines. Fuel pump
The same problem exists in my ATV. I can't find a solution. Have you found a solution?
It is the fuel filter, it works but it does not build up to the required pressure
@@thegreenteam6158 it's the fuel pump yo. Promiss. Just by the kit on ebay. I fixed mines. It was getting fuel just not the right pressure from pump
Did you figure out what the issue was with the start and run?
Fuel pump
I have the same exact bike and the same problem
The fuel pump pressure is way too low
Check air sensor
Or mix sensor
Do you know how to do that by chance?
@@thegreenteam6158 Just because a pump works doesn't mean it has good pressure
. Unplug the sensor, it may then start in emergency mode
I’m going to my local mechanic shop tomorrow. I don’t have a pressure reading thing. So I’ll post an update video tomorrow
Clean carburetor get a new fuel pump
Problem is that its Polaris lol
Fuel filter all day bud
It sure was!
Mine is doing the same. Where is the fuel filter and how much was it?
Sergio Sergio it was the fuel pump, it’s in the gas tank
THE GREEN TEAM Thanks bud!! I just replaced my fuel pump today and runs great again!!! 👍
