Was it sitting outside uncovered? It doesn't start as in you can pull it over and over and still no fire? A little more info would help.

  • #3

It was in the trailer. I have seen where guys say that they didn't idle down before they shut off and had problems starting it back up. I feel thats where my problem lies.

Try that if you haven't yet. Had buddy with 2012 with faulty throttle safety switch.

I have a 14 m8000 that has 300 miles. Rode fri. Rode sat. Tried to start Sunday am (4 deg F at the cabin). No start at all. Nothing. Other 3 sleds started no problem. Had to tow back to truck after 1 hr of trying to start checking everything.
Suggestion that it "froze up". Not sure why a snowmobile will not start in the cold weather...
will update when dealer is open tues. I am not wanting to mess with a brand new sled

I had same problem this morning. Sled sat outside last night in -10 C (14 F). Sled would not start after much pulling. After much pizzing a around managed to get a plug out ( thats a whole other story) plug was bone dry. Shot a couple of cc of mixed gas into the cylinder with a syringe, put plug in, bam, fired right up and ran like a champ. Shut her down and started it up couple of times and she fired first pull every time.
It's like there is no choke, ECU must not be telling the injectors it is cold out.

the older m had problems with the fuel pump.we had a jumper in the tool box and had to run the fuel pump backwords.if it happens again pull the fuel line off the rail and pull it over. should shoot a good stream of fuel.maybe use a can to catch it so you don't have it all over the place.

A snowmobile that doesn't start in the cold. That's a good one. What's next, a boat that doesn't start when it's hot? Haha
I came home and it's above freezing in the sun. Tried again today. Nothing.
I refuse to wrench on a sled with 300 miles!

we get a lot of water in our fuel.when it sits at night ice chunks can get in the fuel pump and not let it work.a drop or two or red bottle heat may do the trick.i also had issues with my tss and had to disconnect it.use a tether instead.hope this helps

That was me, thanks for the attempt. I appreciate you stopping by!

I use startron with each fill and good fuel. I'll be keeping a red bottle with me from now on.
tss was freezing up?

a few of us had problems with the safty switch.dont think it was freezing.if it happens again just pull your fuel line and see if your getting fuel.its fuel or spark?

any update on this? I put about 20 miles on my 2014 m8000. then it sat in the back of my truck for a couple of days. went out to start it last night and it almost fired once, then it went dead. doesnt even seem like its getting fuel now.

I am going to pull the plugs and put some fuel into the cylinder to see if it will fire.

Did you try squeezing the throttle a bit as you pulled it? My 13 did this last weekend, sat out over a cold night. Pulled it, almost fired once, then no go. Had my buddy squeeze the throttle a bit and pulled like hell. Fired up after 4-5 pulls. First time it's done that on a cold start up. Usually have to squeeze the throttle after taking breaks on the hill.

I did try that. maybe i can get a second set of hands and try it again. I used to go through a similiar thing with my 2011 M8 and this is how i would get it started. sometimes it needed just a blip of the throttle, especially after running hard or not letting idle down after running hard.

I also would tun the kill swithc off and give it a couiple pulls, then turn it on and it would fire up.

Try that on the 2014, no luck

pull your fuel line off the top of the pump and give it a pull. If fuel doesn't go squirting everywhere then the pump or smart valves are teh problem. If it does then it's a spark problem

On my sled , something was frozen. A few days warming and no problem, fired right up. Somwhow, May have accumulated moisture. Suggestion was to Use heet in the fuel tank.

What would cause a snowmobile to not start?

Your starting issue could be damaged gaskets or maybe worn-out piston rings, scored cylinder or piston, bad crank seal, reed valve, or a damaged head gasket. Using a compression tester or contacting a place that can service your snowmobile will be the best way to go if the problem looks too serious.

Where do you spray starter fluid on a snowmobile?

Spray it into the carburetor intake and turn the engine. It should start at least momentarily. If it shuts off after burning off the starting fluid, it means you're not getting enough gas coming in.

Why is my snowmobile not getting spark?

Disconnect the main electrical connector coming out of the engine, and then check for spark again. This unhooks the kill switch, ignition switch and wiring for those switches. If the spark improves, the problem is within wiring from one of those switches or a switch itself is to blame.
