2. Remove fuel filler cap.
3. Turn ignition switch "ON".
4. Determine if fuel pump is running by listening for sound of it at fuel filler inlet.
5. Install fuel filler cap.
6. If no sound was heard, measure voltage between fuel pump connector wire (PNK/BLK) to chassis ground.
Voltage : Approx. 12V
7. If voltage is not correct, check fuel pump relay and related wiring harness.
8. If you do not measure 12V, check for continuity between fuel pump connector terminal wires(PNK/BLK) and
(BLK).
9. If there is continuity, replace fuel delivery module.
10. If there is no continuity, repair ground circuit.
