Default Re: Anyone here that can help - pump not activating

Did a continuity test from the plug going to the circuit board on the Blue (Trunk) harness and to the harness end in the trunk going to the pump relay (red & blue) and the level vires (yellow & black).
Looks like I found my problem, I only have continuity on the yellow wire, so it looks like my harness is compromised somewhere. I have started tracing. Just feels weird as this is a car I use 800-1000km pr year and have not done any work on this part of the car for a long time.
