Check compression.

Try shooting some starter fluid to it if it fires you know it's a fuel delivery problem

 

['95Guy]

did both of those, i posted a video in my earlier thread.

Have you checked timing?

 

['95Guy]

not yet (not sure how) but i was looking online and someone had a similar problem and thought it was timing.

Did you check for spark the way I described in my tutorial?

The other thing Ive seen cause no start issues is bad connection or broken grounds, primarily the little wire that comes off the neg cable. It goes to the coil and supplies a direct ground for it, if its not making a good connection you will have spark but it wont be hot enough to fire the fuel.

I checked the spark the way you said and it jumped far enough. So i guess next thing to do is check the timing chain, unless you got any other ideas what it could be.
