Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
Using your scan tool, what desired and actual fuel pressure do you get while cranking?
If those tests pass then I would replace the fuel rail pressure sensor. If metal is round in the regulator, it is recommended to replace the fuel injection pump, fuel rails, fuel injectors, fuel return line assembly, all high pressure fuel pipes, indirect fuel injector, and fuel feed pipes (pump to indirect fuel injector) which are all likely to be contaminated with metal debris.

So far this info is pointing to a bad injector pump. You may have installed a faulty one.
You may want to check it for codes once again, there should be codes stored.
Close off the return line, will this allow the pressure to come up?
