Greetings, thanks for the add.

Traded for a new 2017 450mxui quad.  Haven't used it much, been too busy, but always started and ran fine.
I'm in upstate NY and brutal cold so i decided to move it from outdoor shed to heated barn.
Wasn't sure if it would start - thought battery might have trouble, but to my surprise it cranks fine.
Problem is it won't fire - tried to once but no go.
I pushed it to the barn and thought after warming up it might go - nada.
Almost like there is a safety switch or something preventing it from firing.
Am I missing something why it won't run?

Thought I would check with you guys before tearing in to it.
Thanks for any help you can offer.

    Welcome to the forum, I have the same engine in a side x side, the 450i UXV.  Mine sits in an unheated barn and starts great. I do keep a battery tender on when the cold is extreme as it is now, because I use it to plow snow. As far as your quad goes, does it have an ignition kill switch? Is it on? I guess the real question is..is it under warranty?  If so let the dealer figure it out.  Any possibility the fuel line is frozen?  A quick check of the plug to see if it is wet and check for spark, a nice blue spark is needed. This time of year I do add marine stabil (blue) to the fuel to prevent icing and water in the fuel.
Keep us posted on your outcome, please...

First, check your engine kill switch on the left grip.  Turn the key on, does the fuel pump run?  If no, check the center relay under the right fender to make sure its plugged in all the way.  If the fuel pump isn't running it isn't getting fuel to the injector and it won't start.  I had this last week...
