I've got a problem with the fuel pressure being too high and there is no fuel in the return line. Do I need to replace the fuel pressure regulator?
I'd definitely start there because the fuel pressure regulator, as the name suggests, detects and regulates the fuel pressure in the system. If it has too high of a pressure, then the regulator has gone bad. That's a very common problem. Start there. Generally, a replacement fuel pressure regulator will fix the issue.
