OK so my rebuild of my m52(its in a 92 325i) is finally done and last night I tried starting it for the first time. I turned it over first just to build oil pressure and then I connected all the ignition coils and the fuel pump.
When I turned the key the fuel pump did not energize like it shouldve. I then checked to see if I had voltage at the pump.
I got a reading of 12 volts at the white connector w/ two yellow wires and a reading of 0 volts at the black connector with green wire w/ violet chaser and a red wire. According to the bentley manual I should be seeing voltage there too.
Checked the fuse and its good
Checked relay and its good but its not getting power.
I cycled the key like 20-30 times but still no luck.
So any suggestions to why the relay is not getting power? I have no problem diag'ing it, I was just thinking maybe there was something im unaware of that would be causing this.
