Fuel Pump

  1. Fuel pump is located inside fuel tank. Locate data link connector in left side of engine compartment. Connect a jumper wire between data link connector terminals F/P and GND. See Figure . Remove fuel filler cap. Turn ignition on. Listen for fuel pump operation at fuel filler. Install fuel filler cap.
  2. If fuel pump does not operate, using DVOM, measure voltage between fuel pump connector power terminal and chassis ground. If battery voltage is present, go to next step. If battery voltage is not present, repair power circuit to fuel pump. See appropriate wiring diagram in WIRING DIAGRAMS article.
  3. Using DVOM, check for continuity between fuel pump connector ground terminal and chassis ground. If continuity exists, replace fuel pump. If continuity does not exist, repair ground circuit.
