Good afternoon.

With no compression in two cylinders I would be surprised if it did start. There is a reason for that. It is possible that the timing belt failed and when it did, that failure caused valve damage to the cylinder head.

This will need to be verified.

A shop can do a leak down test to confirm by adding shop air into the cylinder and finding the leak.
