900 Injector Problems

[sledwrek]

Has anybody ever had any experience with fuel injectors failing on the 900's ? If so what are the sypmtoms, and could it just be a seal on the injector? I know the motor has to come out to get access to anything, so just looking for some input before that project begins.

what is the problem you are having

 

[sledwrek]

The sled bogs down and takes a long time to build any power when you give it gas. It has been at 2 dealerships now, the first guy spent half a day on it checking codes and replacing parts, and the second guys are still working on it. We have already changed a ton of parts chasing this problem, we are almost down to the injectors now...getting pretty frustrated now.

I have heard of injectors getting plugged from the float deteriorating in the fuel tank and particals will plug the injectors. The fuel tank float was recalled for the 05 900 I think, or suggested to be replaced.

also for the 06 they replaced mine

 

[sledwrek]

Yeah that upgrade was done to mine as well...did fuel filter, checked fuel pressure, eliminated all exhaust valve related issues...I dont know what this things problem is. Even the dealer is confused...

is the clutch sticking?
is there a air leak at the intake area?
Did they test ignition?

 

[powder junkie]

clutching is a good place to look. blockage in the exhaust system? sumthn wit the computer maybe not firing all 4 injectors? (if urs is the 06)

 

[sledwrek]

Replaced a cracked intake boot, does the same thing with the clutches pulled off and just the machine revving. Hooked a test light to both cylinders and they are firing, pulled the can and pipe off and it is the same. Adjusted throttle position sensor too...I dunno. All signs seem to be pointing to injectors, or injector i guess. Its a 2005.

 

[BRP QSC]

fuel pressure?... plugged fuel filter... two dealers...someone would have checked that im sure

 

[sledwrek]

Fuel pressure was good still, and put a new filter in it...

Has the timing been checked? Just a possibility.

Does anybody know if there is a way to test the injectors once they are out? The engine is pretty much out of it right now, and new injectors are $700 for the pair, seems like a pretty pricey gamble to see if they work or not.
