Does anybody by chance have a wiring diagram for the plug going to the fuel pump? I'm not getting fuel pressure and can't hear the pump run, however I just replaced it last fall. I would like to make sure it's the actual pump before replacing it again, I'm worried that perhaps it is the non-serviceable relay 303 or some other component. I pulled the tank down some last night to get to the harness which has 4 wires. I tried testing every combination of them to see if I got 12V when the key was first turned to on but didn't have any luck. I would really like to know which wires I should really be checking before going in one direction or another. Thanks for your help, I used this site last time when I had to replace the pump when I found a great write up on how to. Thanks again for that.
