So I went ahead and made sure my battery was charged and took out my multimeter.

I took off the cover for the fuel pump under the rear (passenger side) seat. It looks like I have a single connector. But according to my Bentley service manual and this guide: http://www.pelicanparts.com/BMW/tech...eplacement.htm, I should have two separate connectors.

(more info after the pictures)









The service manual doesn't show the pinout for the connector, so I'm taking wild guesses and checking the voltage on every line. Does anybody know the pinout of the harness? I noticed this red/white wire shows 0 volts even while trying to start the car.





Correct me if I'm wrong, but I believe the e9X uses a fuel pump "control module" instead of a relay? Should I work backwards and begin checking power at the control module? Thanks for all the advice so far guys!
