Ah, red label. Sounds like something isn't wired correctly. Don't mess with fuel pump wiring. I assume it worked fine previously, highly unlikely that is culprit. I believe there is a black shielded wire that you also need to connect by the fuse box. Use this swap thread: https://www.bimmerforums.com/forum/s...er-Swap-Thread

Also check photo of bay on page 2 for some wiring.
