Nissan: Replaced Timing Chain now engine won't start

I have a 95 Nissan Sentra and my timing chain went out. When I say "went
out" I mean when I opened her up to check it out all but one gear had
anywhere from 3 teeth missing to one with all but maybe 6 or 7 missing. I
guess it is safe to assume it must have jumped time when she finally quit. I
did try to start it several times after it quit, but I never heard any bad
noise. A few people tell me that it is not possible for the valves to hit
the piston in these newer models, but I am not so sure. Anyway I reassembled
everything and it not only doesn't start, it is as if there is no
compression because the engine turns so easily, almost as if it is only the
starter turning. (Yes I have checked and the engine does turn.) I know the
first thing most of you will say is that it probably isn't in time, but I
have checked it and checked it and by the Haynes and Chilton books it should
be in time. I am certain in my mind that it is in time. All I can come up
with is that at least one valve in each cylinder must be warped for it to
have zero compression. It doesn't spit, sputter, or anything! I guess what I
am trying to ask here, (and not wanting to hear the truth I guess hehehe),
what are the odds of the valves and/or pistons being warped or damaged to
where I have lost compression on all cylinders?

Thanks for the replies guys. I guess I'll have to save up for a new engine.
I was afraid of that. :-(
