Yep, I'd investigate the timing belt/cam first. Who replaced the timing
belt? The 1.6L & 1.5L engines have different cam pulley alignments for
proper belt installation/timing -- see
http://www.cadvision.com/blanchas/54pontiac/honda.html -- and it wouldn't
be the first time somebody got it wrong. Hell some goon "mechanic" once
lost the crankshaft pulley key and the pulley was not aligned on the
crankshaft.

Are you sure you're reading the index mark and notches right?... no fancy
advance thingy built into the timing light which needs to be disabled?
Engine at normal idle of 700-800rpm? You're supposed to jumper the service
connector too but it's been said it makes no difference below 900rpm -
which I found to be true. Not sure what you mean by "above the pointer"..
the strobe goes off with the pulley marks to the right of the index mark...
i.e. advanced? With timing that far off I'm surprised the thing runs at
all.

On my Integras it's a 12mm and yes, if they haven't been loosened in a
while, it'll take a whack with the heel of your hand to get them off.
