I bridged the female part of the socket from the 1 port to the 2 port with a bit of wire. This resulted in fuel pressure at the injector. I assumed that meant that the MAS module is faulty so I replaced it. Now I am back to having zero fuel at the injector while cranking. If there are no other components involved I am beginning to wonder if it is likely that the fuel line is clogged, perhaps at the filter? Does anyone have any ideas?
