So the fuel pressure leaks down even after the fuel pump and injector assembly have been replaced?

Customer: replied 26 days ago.
that correct

And there are no external fuel leaks?

I smell an gas odor but no visual leaks, eventually the engine hydro locks

Ok, then there is fuel leaking inside the intake. It is possible that the new injector assembly/fuel pressure regulator is faulty.
