OK, let's clarify some definitions here...

Doesn't turn over= doesn't rotate at all

Right?

Do you have an inductive timing light? If so, install it on a leading plug wire. If not, pull a leading plug, reattach it to the wire, sit it on the engine, and crank her over again. See any spark?

To start you need:
cranking RPM's >150
Compression
spark (properly timed)
air
fuel (not too much)

(At least with a Wankel you don't have to check valve timing.)
