Cranks but will not start?

It sounds like the timing belt can be worn and off a tooth or two I can tell if you upload a short video of the engine cranking so I can see it. That way I can tell for sure what's going on. You can upload it here with your response. Also, I would put your hand (with a gardening glove) over the exhaust pipe at the rear of the car when it is cranking only to see if you feel the pulses of the engine or if it barely comes out? You could have a clogged catalytic converter.

These guides can help us see what's going on:
