Oh, so they were removed. We pulled them out but still all attached to the rail etc and put a towel under them, and turned the car over. Visible fuel came out.
Doing it this way ensures that the car's entire system is in play; this may help you. We pulled the connector to the coil so there could be no spark while this was happening, so no chance of starting a fire.
In this case, the cam gear pin had broken.

It seems you have fuel, spark, and compression, and the cam is turning. So if you do the above test and there is still fuel, there is something very odd going on.
Have you checked that spark timing is happening correctly?
Also, I wonder if the cam belt skipped some teeth, so even though it's turning, compression is not happening at the right time either.
