Won't stay running pro 800

Twostroke · Apr 1, 2014

2011 pro, 2,700 miles, has been running flawless. Randomly died after coming to a stop to check on a buddy and wouldn't restart. Towed it out.

It fires but dies.

Replaced the fuel pump and same thing.

Ideas?

Have you checked compression?

Sounds like a TSS or Tether issue.

Did you do the fuel filter as well?

The killswitch is broken in the throttle block but it had been for months, could i disconnect it to rule it out?

Yes

There is 3 wires coming from the throttle block, how do i tell which is the kill switch?

I have my own sleds to work on any ideas are helpful, looking at this for a buddy.

I like carbs, minimal electrics, and hoods that have a hinge, glad I don't own one of these. :face-icon-small-sho

Unplugged kill switch, it fires but will not stay running..

What's next to try?

PaasoRacing · Apr 19, 2014

You can't just unplug the TSS, it either needs to be working correctly, taped down, or bypassed with a resister.

Could it be the problem?

Which of those things is easiest?

Pow forecasted all week here and this sled is my main riding partners!

if you are still trying to figure it out have a look at the capacitor. Black box that sits on the clutch guard. Had one do the exact same thing and after checking everything over as far as tether and kill switch it ended up being the capacitor. You can test it with a digital ohm meter.

I had the same problem, first hold in the throttle safty switch while starting, if you can keep it running while using throttle and it dies when u let off its likely a tps issue. If that doesn't work you could have an injector problem which isn't uncommon on that sled.

Had Mt.hood polaris scan it, bad ecu. Extended warranty is covering it.

Turns out mt hood polaris can't find there way out of a paper bag just like my local dealer.

Sled is still not running.

They think it's the voltage regulator now, don't have one in stock and won't try one off one of the numberous pros they have in stock..

Snow is melting and this sled was suppose to go to montana tomorrow and ride this week.

Fuel pump is not getting voltage is the problem, the voltage regulator is the first thing that came to my mind when I heard that from them last week but what do I know they are the professionals, I guess that's why it's been 5 working days and it's still not running.

All I can say is you went the wrong direction for a dealer

I had a similar issue with my 2011. That was at the end of the season and I did trade that one in. I did hear a rumor later that it was an injector(s) but I can't say that for sure.

Greg, this is a buddy's sled. I told him to take it to you but it just happened I was going to Portland so that's how it ended up at mt hood. You actually may be seeing this sled soon because he's getting sick of waiting on poor service from dealers!

Did you figure out what the problem was? I have a 2013 that sounds like it went down in the same fashion. It ran great all weekend, then about a mile from our hotel was doing a little climb and just died. It will start and run if I holdthe throttle but as soon as I let off the engine light comes on and it dies.

it was the stator
