I did another fuel pressure test now that I have a new fuel accumulator in the line. The fuel pressure on the main line did not go over 4 Bar. I think I am going to close this chapter and competition and call it fuel pump problem. It's new so I called the vendor and this time they took my car's serial number. Guess what, I had the wrong pump all along! A whole year of misery and all it was is the wrong part.
Thanks guys for your input.
