Hello. My name is Mark and I will be assisting you today.

First thing to do is check the compressions. Even though timing looks ok now, who is to say it wasn't set correctly to start with and then redone.

Compression was checked and is ok,fuel pressure is ok,egr valve is ok,

The next thing I would try is to disconnect the exhaust and try start it. Possibly the catalyst is blocked.
