Before changing pumps, though, I'd do a confirmation test. The best test is to make sure you have pressure (2.5 bar) at the fuel rails via the test port shown here:



If you don't have a fuel pressure gauge, a true Dorki style ghetto test would be to remove the test port cap, hold a cup under it and have a helper jumper the fuse. If the pump works, you should see fuel flow. If not, you get nothing. If you do this, obviously be careful with the gasoline but also make sure not to lose the little ball bearing that's inside the test port cap.
