Let's try and figure out what it is missing. Does the engine turn over like it normally does or is it slow and sluggish. Turn your headlights on and try to start your Armada. Do the headlights dim, does the radio stop working etc.when you try and start it. If yes, then this could be a battery issue but it could also be a starter issue (drawing to many amps) Go ahead and try the boost as previously suggested. BTW, also check your battery cables. If they are severely corroded, you could have the same starting problem.
My concerns is the tick, tick, tick noise. This could be a fuel pump issue as well as a relay issue. Let us know what general area you hear the ticking from. Onc we know that your engine at least turns over and tries to start we can get further into this.
The air will be last, once we got your issues narrowed down and know more about what your Armada does.
