Not having a correct ground will do that. So make certain that your alt and batt ground are secured tightly. My batt cables were not on tight enough and I was certain they were, as I parked and it didn't start.
How old are the cables? Poss you may need new ones?
If that's good and you say your fuse link is good I'm opting for fuel or spark.

Pick up something like this at your local autoparts store
http://www.autozone.com/test-scan-an...der/222498_0_0
There is a data port under your dash that this plugs in to, turn the car to ACC and scan the codes. It will ouput things like P0031, p1234, etc. Those are the codes, you can look them up and, if you have one, it might tell you what is wrong.

The only issue I have with that statement is that I don't even hear the car trying to turn over whey he hit the button.
You didn't happen to accidentally plug the battery in backwards after reinstalling it? Or did you not disconnect it while replacing the alternator?

Battery was put in correctly and I disconnected the battery for 20 minutes before touching the alternator

I just watched your vid, and it has to be electrical if it is NOT cranking at all. Ing fuse, solenoid fuse, and starter relay need to be good. Is the voltage reading properly from your batt? Have you tried jumping it as well to see if power is the same?

My brothers 350z did this months back. He pulled into the gas station it never started back up. It ended up being the starter. We lifted up the car and located the starter gave it a few whacks darn thing cranked right up. We tried first all methods replaced battery, checked grounds, replaced corroded negative cable. Car would still not crank or you couldn't even hear the starter click. Got the car home and turned it off wouldn't crank again. Like is said it ended up being the starter.

My car used to start with a jump when my alternator was bad, take off the cables and the car would die.

I have replaced my alternator as well so i have to say did you plug the cable back in that is on the alternator? I almost forgot mine and not saying you didn't plug it back in just asking because it is a small detail that could be overlooked.

If one part of the fusible link blows, does the whole fusible link go to? This is the voltage im getting as someone else is attempting to start the car

I would bet it is the battery, Had the same issue everything turned on but wouldn't start. I charged it overnight with the ground off the battery so the car couldn't try to do anything, In my case the car was still in the On position and was causing the charge to not go to the battery but to try and power the acc. after I charged till it was a solid 12v then plugged the battery back in it started fine.
