- Connect data link connector terminals FUEL PUMP and B+ with jumper wire.
- Remove fuel filler cap.
- Turn ignition switch ON.
- Determine if fuel pump is running by listening for sound of it at fuel filler inlet.
- Install fuel filler cap.
- If no sound was heard, measure voltage between fuel pump connector wire (PNK) to chassis ground.
- If voltage is not correct, check related wiring harness and repair as necessary.
- If you do measure 12V, check for continuity between fuel pump connector terminal wires (PNK) and (BLK).
- If there is continuity, replace fuel delivery module.
