Is there a reason my 2012 600 switch wont start right now. It floods. I unplug fuelpump and itll fire up for short time then run out of fuel. Plug in pump and itll fire up for a second then die. It floods out. Too warm out? 25C
sled no go
- Thread starter pulltype_polaris
- Start date
The only thing the heat will do is make it run rich since the sled needs less fuel, which is a possible reason you are having issues. Simple way to check is look at your plugs, if they look even close to right, basically as long as they aren't fouled then running to rich due to the tempeture has nothing to do with it (or it shouldnt anyways).
Itll literally run for 2 seconds then die. Plugs are wet. Unplug pump and itll eventually run for another 2 seconds. Any throttle and it won't run. Like tps sensor or injectors. I guess I could check fuel pressure too. It ran a month ago just not now.

New set of champs and new set of ngk. Thinkin its time to send it in to get scoped.

So you probably already checked the spark?
Good spark. I can get it to run and as soon as I plug in the pump itll die and plugs are wet.
Sounds like a bad injector. Is it both cylinders that are flooded?

That's a tuff one sitting here but Just sitting a month and running good before makes me believe it something simple,with bad gas it should at least run unless you got a big dose of water in the fuel.
It seems like one is maybe worse than the other but both get pretty soaked.
Fuel didnt smell bad but I added some av gas to top up octane after I had troubles. I was leaning toward injectors. Ethanol is the devil. Not easy to get non ethanol fuel around here.
lightly tap on the injector bodies..sounds like one has a stuck pintle....(try the one that looks wettest first)..most likely a stuck injector..whenever you park an injected motor..good idea to pour some 2stroke oil in the gas along with a can of seafoam, run till its circulated..then park...

Bad injector is a possibility but now that you mention ethanol i would check for water in the fuel.

Sounds like injector is stuck open the temp outside doesn't matter i just fired my pro up today and it ran fine at 24C outside. Try tapping on it like suggested in the other post.
By bad injector what do you guys mean?
As far as ethanol ive had issues with my mx bikes and had ethanol partially clog injectors. It just wouldn't get enough fuel and run odd, like the choke was on but there is no choke. On them (Suzuki rmzs) you simply pull the injector out, hook it up to a 12volt power source To get the injector to open and blow them our with compressed air and your clean again.

Injector is stuck open, flooding the engine is what I mean by "bad" injector. It would cause an excess of fuel to be delivered when it shouldn't, causing the motor to flood. Hence why he can start it for a couple of seconds if he unplugs the fuel pump.
