2011 Nytro 240 Problems

[Poindexter]

Last winter I was riding hard with my Nytro and right before I got home I just had to do one more wot before parking, but right when I let off the throttle it started to sound really weird, like a phazer without turbo. I let it cool down and shut it down.. Tried to start it again and it was struggling really to start and when it started it still sounded bad. Checked the plugs and saw that the one plug that was closest to the clutch was really wet, and smelled gas. Took out the rest of the plugs to try to turn the engine and it sprayed fuel from that one sylinder.

I have tried to check the compression and test each injectors by myself, but I have very little experience with injectors, or troubleshooting in general.
Does anyone know what it could be and how troubleshoot it?

Get into diagnostic mode
Test injectors, and plugs and so much more
Disconnect your external fuel pump prior to commencing

I will try it.
