Can't push lever to shift into big ring, lever will not move all the way I just installed a new 6800 groupset on my bike for the first time, and everything went O.K except for the front derailleur. I can't shift it into the big ring, if I push the lever to change to the big ring, it won't go all the way, and it won't make a click. 

If I push just the smaller lever (to get into the small ring) it makes a click just fine, but if I push the big lever, it will move a bit but not enough to click. 

If I disconnect the cable from the FD, I still can't get the lever to move and make a click. Is the cable stuck somewhere?
Check the limit screws -- if you set them in the wrong way they might stop the full movement of the cage, irrespective of the cable.  If the cable is disconnected and if you cannot move the cage so that the chain goes on the front outer right that is either because of limit screws or the bottom bracket is so far out the outer ring cannot be reached by the cage.

Check out this page and see whether you get something out of it:

PS as PeteH mention in his comment, if you cannot 'click' the levers, check whether you have installed the cable correctly -- I personally think this is a very unlikely situation, because cables can normally be installed only when the shifter is in one specific position.  Worth a check though.
