replaced valve cover gaskets, now won't start

[nika-tika]

I just replaced my valve cover gaskets on an 88 ranger V6, 2.9.
Now it will turn over (pretty fast) but wont start... I'm pretty sure I put everything back and distributer cap looks fine. Any suggestions?

I pulled the center wire on the distributer cap and checked to see if it was sparking when the engine was turning over and it isn't...
