I would suspect a crankshaft position sensor. If you are trying to fix this yourself, get a can of starting fluid. Open the air cleaner box, remove the filter and spray starter fluid into the hose leading to the engine while someone cranks the engine for you. If it starts and runs for a few seconds, you have a fuel problem. Maybe a pump.

If it doesn’t start, check for spark. If there is none, I’d really suspect the crank position sensor. They are about $50-80 but I have no idea where it is located on a rotary engine.
