1. Remove the fuel pump relay in the Underhood Electrical Center (UHEC). Using a suitable jumper short terminals 30 to 87. Verify the fuel pump runs.

2. If the pump does not run, verify battery voltage on the jumper. If OK check connector C301 near the AntiLock Brake System (ABS) module on the left side frame rail under the driver seat.

3. If the fuel pump runs, install a test light between terminals 85 and 86. Turn the key on, engine off. The test light should light for 2 seconds and go out.

4. If the test light lights, replace the fuel pump relay. If the test light does not light, verify a good ground on terminal 86.

5. If the ground is good, check terminal 85 the DkGreen/White wire to pin 1 of the Blue connector at the Powertrain Control Module (PCM).

6. If the wire is good, verify connections. If OK, replace the PCM.
