The issue was that my timing was off quite a bit (-30* bank 1, -22* Bank 2). I had to use a snazzy Snap-On diag computer and some time. After a quick search, I discovered that my cam phasers were seized. I changed the cam phasers and set the timing back to spec (10hr job and those fu#^ers are expensive new). The service manual is also a huge help. Now the car starts right up, as it should. I hope this helps.
