Polaris Sportsman 450 / 570 Not Starting??? ABSOLUTELY MUST SEE THIS 

Great video. Have two Sportsman 570s (2023 & 2024) and came across this video while looking for maintenance tips. I'm sure this will be handy down the road.

Gonna try this today. Great video fellas, good narration and explanation. Link info to the tools was awesome as well. Subscribed. Thank you.

Great video, thank you. Ordering the topdon tester too. Subscribed.

Excellent video, subscribing for sure! Another easy way to see the low battery condition if you don't have a multi meter or tester is the control panel on the headlight pod. When cranking it should not cycle on and off. With your low battery it was cycling on and off during cranking, but with the new battery it stayed on. It's not foolproof, but could help to point a DIY'er in the right direction. Note, the 2021 and newer units have a battery tender port on the headlight pod, which is a great way to prolong the life of the battery (as much as possible anyway).

Really excellent video, you are both really good at this. thanks bill

Great video! I will be trying this in a couple of hours.

This really worked on my 450 2021 thank you guys

Thanks for the info

Awesome Video thanks guys

Your great narration and detail info convinced me to subscribe.

Good job fellas. Not bad. Put your meter back on the old battery. Crank it over. Watch the voltage drop. If you drop under 10 it will not go. 10 is the threshold for the ecu.

My 2009 sportsman is doing the crank no start. Is this the same sequence you’d recommend for that year?

Today my ATV just up and cut off on me lost all power instrument panel cut off and backfires is it my battery or is it my coil or is it a combination of both and for the record mine is a Polaris sportsman 450 ho efi 2017 and I had just changed the fuel pump spark plug and wire and the air filter

Thank you

This video helped me with (possibly) selling my ATV. The buyer came to pick it up and even though it started an ran for me to get it out of storage, it did not start later. The buyer shows up, pays me for it. Then starts is once and it dies, never to start again. I refunded them their money and offered to get it running and deliver it the next day. I am now waiting on the buyer to except that I fixed it. The problem was the battery was low from me starting it just long enough to move it into the yard for sale. While the buy was trying to start it I noticed on the screen it showed what looked like a low voltage reading like 10 then 9. Even though it still cranked it would not start. I removed the battery and put it on trickle charge for a while. Then bumped it to 40 amp for 5 minutes. Removed an cleaned the spark plug (could not find the new one). Reinstalled the battery and the cleaned spark plug. Starts and runs great. Thanks for your video.

Have a 2020 sportsman 450 that wont start and sounds like this. Brand new charged battery and sparkplug, still wont start. At first it woulf fire up, run for a few seconds and cut off, but now wont cut on at all. I tried octane boost hoping if theres a clog in the fuel pump or injector that it would clear. But still wont start. Im stuck and not sure what to try next. (And yes, mine has the battery underneath the front and it is the BIGGEST pain in the ass everrrr)

My Polaris is doing that it'll fire up then stall then go crank no start but can leave it for a few hrs fires right up without doing anything to it

My scrambler 2013 850xp wont start when i turn the key all i here is a tick sound my lights and everything works

My 2017 450 Polaris is Stil not starting!! I’ve change the battery to a new one and the spark plugs ! Stil nothing what else should I do ????? Fuel pump is working also!!

Nice video really liked the funeral music

Yeah it’s usually the battery I have a 2014 I put one battery in per year but mine’s got 7K plus miles on it

I have a 2014 polaris 570. The battery is a PITA to change. #1 Interstate batteries are garbage. #2 You should have put dielectric grease on the inside of the spark plug boot after you installed the new sparkplug. Just my opinion. Opinions may vary. Have a nice day 😊

is 300 rpms to low when cranking it?

I have a 2022 450 sportsman I’m getting no spark I changed plug still have no spark helppppp

Mann I have both replaced the battery and the spark plug nothings happening. My polaris trail boss 2005 sucks man.

Easy access to the battery

If my battery’s low, can I boost the battery to see if it starts with a new spark just to see if it starts

The Polaris Sportsman, do they all make gear noise, and hard to get into reverse?

What if it starts then shuts off after a few seconds? New battery and plug.. Only way to get it to run is if I open up the throttle a bit and go, then it runs fine.

Can you do a quick fix video for the new recall on the Sportsman 450. It says it’s just taping some wires but i’d like to make sure me and everyone else is doing it properly. Thanks guys.

Guys that know what they are doing! 🎉 Maybe you can help me, my 570 ( 2018 model) just doesnt want to crank 7/10 time. When swithed on, the zzzz sound sometimes happens, sometimes not ( guess it is the normal feul pump operations) but then when turning the key to start, just nothing. A couple of on/off and the suddenly it starts. Battery is new. Could it be a dirty fuel filter or the handbrake switch that the control box just doesnt give the start command through? Thanks.

I have a 2018 570 sportsman. Have changed battery and plug, got a good spark and still no start. What next.

What would be the next step you guys would recommend if the battery is good and you replace the spark plug and still getting a crank no start?

The fix is trade in for a CanAm! For sure fix!

Mine ran out of gas and now it won't start at all t will turn over but I'm still thinking it's the spark plug

The background music is driving me up the wall.

The 2020 450 HO is a piece of junk man....CONSTANTLY breaking down, dies randomly. The engineering is dogsh#t 😑

What's with the Mr. Softee Ice Cream tune in the background. Every fuqn generation is getting worse. WHEW!.

Sounds like bull for most part.

Polaris = overpriced junk
