motor wont turn over?

I agree with ramcharger - if the only thing you changed was the timing chain - and no other parts, your cam timing must be off somehow.

You can eyeball check this by looking at the tdc mark and cyl # 1 exh and intake valves, if its in synch the exh and int valves should be closed on the compression stroke for cyl 1 firing at TDC, dont forget there is an exhaust stroke as well.
