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

markthebooler :

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.

Customer :

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

markthebooler :

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