Engine will not start when hot without adding starting fluid to th air intake. Have changed the fuel pump, oil pressure sending unit, spark plugs and ran injector cleaner thru it so far with no change. Same problem still exists. Starts OK when engine is cold.

OK. I'm starting to realize that you guys are no help at all. I'm also a ASE master tech with 50 years experiance so I don't need the basics. I'm trying to solve a wierd one here.
