Re: 2010 razor will not idle

Does it run fine otherwise? Normally and I say normally a weak fuel pump allows it to idle but not come to speed.

I would say a place to start looking is the throttle sensor voltage out of whack or a issue with the idle speed control valve.

Re: 2010 razor will not idle

our 09 did that one day ,I changes spark plugs, and checked most everything short of actual TPS voltage, as I went to loosen clamp where T.B. goes into intake boot from air cleaner to clean it, the T.B. just feel down, turns out if was lose/slide out of the intake manifold side already. put it back into intake boot on engine side, tightened clamp, then back in intake boot to airbox, ran like new again.

on a sie note ours had been idle-ing low like 950-1050 rPM's after the intake boot fix that was lose, guess got loser/came out finally that day messing up its idle sucking air into engine there. it also fixed the low idle.

Re: 2010 razor will not idle

Thanks for the help. For the most part as long as u stay in the throttle it runs ok, little on the rough side but will run. As soon as you let off the gas it shuts right off. Does any one know if a fuel pump out of a 2011 S will fit. When i cross reference the polaris part#s they are not the same but is that the case, or is that just a polaris thing.
Thanks again for the help.

think for an 11 or 12 pump to work, you will also need an 11 or 12 fuel tank too

Re: 2010 razor will not idle

Have you checked the fuel pressure or the TPS voltage yet?
