So here I am, working on a 2007 Outlander 800 XT...and it seems that the laws of physics have vacated cylinder 2. I suppose I should start at the beginning, before we get to the good part. This machine was brought to me as a no-start. 2761 miles/391 hours. Came up with a cam phase sensor code. Pulled the cam sensor, and looked inside to find no movement on the cylinder 1 cam gear. Timing job...no problem. Tore it down. #1 chain had broken. There were marks on the piston from contact with the valves, but very slight. The valves do not appear to be bent, and seat up with the head perfectly. #2 is fine, chain stretched, but intact, and no indication of interference. Order chains/guides, gaskets, oil, and filter. Install the new parts...double and triple checked timing. Adjusted valves, new NGK DCPR8E plugs. Starts fine, but runs rough, and is the new 'Gutless Wonder' trophy holder of the neighborhood. Cylinder 2 is not firing...at all. Things I have verified/checked again -multiple- times: both timing chains set properly - valves adjusted properly - strong, consistent spark on 1 and 2 - both injectors spraying properly/equally(also swapped) - no diagnostic codes showing - muffler cleared of carbon... No matter what I mess with, absolutely no fire in #2...as in, exhaust pipe at the head stays completely cold until heat makes it's way up from where 1 and 2 join up. Someone please point out if I'm missing something, but fuel and air go in the bedroom...spark falls through the window whilst peeping...physics demands that some kind of energy runs for the hills as heat. The -only- possible exception I can come up with, would be if somehow, the computer caught a case of the dumbs, and were sending spark at the end of the exhaust stroke - only to number 2. I'm absolutely perplexed, and completely baffled. With a large side helping of flabbergasted. I really hope somebody here can offer some insight. I wait with bated breath.
