First:
Did they eliminate Fountain of Youth with GnK?
No. And it could be indirectly rarer to find in GnK simply due to the addition of so many new faith natural wonders.

I've seen them a few times, but in my current game, I found 3 lots of techs ! AH, Sailing, and Masonry !!
I've never seen the fountain of youth either...

Just last night I got 3 Faith ruins in a row again. I'm playing a Marathon game, so the magnitude of the ruins is greater. The first had 80 Faith and scored me a Pantheon. The other two were 190 Faith each. I'm well on my way to founding a religion.
Oh, and I'm playing the Byzantines.
This is shocking. Are you using a mod or doing something else unusual?
Nope. I usually get at least 1 Faith ruin per game. It's unusual for me to get none. I do like to run 2 scouts so I can find as many ruins as possible.
Wow. What maps and settings (aside from marathon) are you using?
Wargizmo, I don't think that is correct. I've certainly found faith ruins early on- although not very often.
Secondly, I think it is more likely a random generator that gives you whatever rather than having a preordained reward. For instance if you have a weapons upgrade you'll never get another one with the same unit so if you pop another ruin a weapon upgrade must be taken out of the generated reward list.
Maybe someone can answer with a bit more certainty though.
