Trickle charge your battery whenever its parked for a few days, efi needs a good battery.

 

X 2 EFI needs good charge in cold weather

 

I also use a trickle charger on my Atvs during the winter.

 

Something doesn't sound right started mine all last winter here in Alberta never a hitch took right off every time

 

Last fall hunting at -35 buddys commander always started easy.

 

My commander started without any problems throughout our Canadian winter last year.

 

No problems starting here either, what are you running for oil in the crankcase?

 

I also have this problem when I'm at 7000 ft. or above. no problem when at home 5500 ft.

I kinda feel this is the problem but when I'm 9 and 10 thousand feet it runs and starts just fine????? who knows?

 

Duluth Winter starting

I live in Duluth Minnesota, -20's last year no problem with starting ever. Sounds like a battery problem, either trickle charge it or replace with a strong battery.

 

Thanks for all the replies, I trickle charge my battery, my battery is strong, my oil is the recomended BRP all season oil, i feel it's an altitude issue maybe but once it is running it runs great. Thanks for all the feed back I hope to get it figured out cause it's kinda pissing me off if you know what I mean.:huh::rating06:

 

follow up on cold weather starting 2011 800 commander

So I have been trying to figure out my could weather starting issue and here is what I've done and am figuring out.

It has been 20 degrees at the cabin the last few mornings so I leave the machine out all night. In the morn I start it and of course it won't start, it kicks over strong but won't start. So I have figured this so far I start it and it won't start so I pull the key out wait a minute then put key in and it starts right up? I very cold blooded but the key thing really makes a difference? Why? Anyone experiencing this? I still feel the high elevation has something to do with it? Can that be adjusted because it's fuel injected? Any suggestions I would love to hear it.

 

FWIW, I live at 8000 ft. My 800xt started just fine all last winter with temperatures well below 0F at times. So, not sure that altitude would be the problem or I would have seen some issues as well. No suggestions, but possibly something with the computer system since your key seems to affect starting? Something specific to your machine?

Sorry that I can't help more than to let you know that my machine starts fine at altitude at low temps.

 

Thanks Saintly Brees I appreciate the info

 

I live at 6000' and it gets down to -40. last year it got down into the -30 and mine starts fine most of the time. Once in a while you turn the and push the bottun, and nothing no click no anything. The dash lights upand starts scrolling through the greating but nothing else. turn the key off wait 5 sec. and turn it back on and hit the button and VVVVVVVVVVVVVVVVVVVVVVVVOOOOOOOOOOOOMMMMMMMMM. don't know why. Could it be the same thing I don't.

 

things turnover easier with synthetic oil too when its cold

 

That was a bad O2 sensor on my Spyder (also a Rotax)

 

Dragonrider,
Did you replace the O2 sensor or have the dealer do it? Did you discover that problem?

 

Maybe need to replace the battery ?

 

I might have missed something but you say it turns over strong but won't start. But if you remove the key wait and reinsert it it will start. It sounds like the system isn't recognizing the chip in the key at times and not letting it start.

 

The Battery is strong and new it's something with the key but now that it is back down in the valley it starts just fine. I'm confused?????

 

I have changed my key but I'm not in the mountains with colder weather right now brought it down to service it and right now it is good to go, I'm not sure??

 

Make sure your headlights are off before pushing the start button. Let all the battery power go to the starter instead of sharing with the lights. After running, and idle settled in turn on your lights.

 

And wait til you can't hear he fuel pump.

 

Mine has been a little slower rolling over now with -15c temp, and when its running untill it warms up it stays in limp home mode. No clue why, only thing different this year from last is a custom intake just like the utv inc one, and the hmf swamp series xl exhaust.

 

The suggestion was made to check my fuel pump pressure cause some folks have had issues. My fuel pump pressure is right on at 50 psi. Right now its been cold but my machine is not at 8600 feet and right now it's starting just fine. Any way I sure appreciate all of your input it has been helpful cause it has forced me to really dig into my machine and at this point I believe I have torn into just about everything on it. Thanks to all and be safe in your riding adventurers
