I cant seem to figure out the electrics of my 1981 320i. If anyone knows how the fuel pump relay should work, I could sure use some help. With the key on, I get power at terminal 87, no power at terminal 15. when I try to start, I get power at 31, no power at 31b. Is this right? Also the inline fuel pump has no power to it, but the internal pump does. If I jump power to the inline pump, I get fuel. Any knowledge would be very appreciated. Thank you

Now I seem to get the pumps to turn on and fuel pressure is UP at the distributer but I don't get anything through the distributer? Any suggestions?
