Still sounds like a timing issue if your are getting fuel. Have you checked your fuel pressure?

no start

If you put new plugs in they might have given you the wrong ones. cross reference to another brand. Happened to me long ago. Once upon a time I got a 57 chev that someone had put a new cam in. But it was the wrong one. It was off just enough to make everything appear right but it would not start. Plugs a good possibility.
