Check the fuel rail to make sure that there isn't anything obstructing the lines flow. Follow the line getting pressure until you are not getting pressure anymore and investigate that area. When you remove the regulator, does fuel spray out when you pressurize the line? I feel like there is a line blockage somewhere, maybe even on the return line?
