2000 GMC Yukon V8 Two Wheel Drive Automatic
The fuel gauge constantly reads empty with the low fuel warning words in info box. The fuel unit in the tank is New. I used the best wiring diagram I could find(Clilton's, and online AutoZone.) The Purple (ppl) wire has 5 volts reference with key on and I connected a jumper directly to the Org/black(org/blk) wire and still reads empty. I need help on what to do next. The wiring diagrams are in conflict one saids go to the ECM other go to BCM. Which one and which wire? Is it still the org/blk to check?
