I was hoping someone could steer me in the right direction on this.

Long story short....my brother twisted the frame on my CC this winter and I just finished the tunnel, frame and front suspension replacement; along with $5,000 of other needed parts. Everything was removed and either replaced or reinstalled. Running fine prior to disassemble.
Finally got everything together this past weekend, filled all fluids and turned the key.....nothing but a quick pop. Tried this numerous times until I created the loudest back fire I have ever heard. Soiled myself a bit.
I tediously put everything back together as I remember...however, still no fire up....just a quick pop like it wants to start, but nothing further. Could I have the coils wired incorrectly? It almost sounds like the spark is not hitting TDC, but rather the opposite. The entire engine and wiring harness came out as a whole...so not everything was disconnected....coils, yes.
Any assistance would be appreciated.

Thanks!

Pull the plugs. Does it have spark? I don't think you could mix up the coils. If it's got spark, then pull the fuel line off the rail, or at the pump, carefully pull it over and see if you have fuel shooting out. (Don't let the fuel hit the spark!). If it has fuel and has spark, it will run. Install new plugs, tap the injectors....maybe they are stuck. Then spray a shot of gas into each throttle body. (Clamp throttle open, spray gas, Unclamp throttle, pull rope). If it Runs and then dies, that would be a stuck injector.

Thanks for the info guys! I ended up having the coil wires crossed. Runs great now.

The frame got twisted while running the power lines in 3'+ of snow and hitting a buried 4' vertical cut of ground drifted over. He hit it with the left ski, twisting the front suspension and chassis, along with damn near everything else!

Yes...I know. Stay on the trail.
