Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel Pump Relay
Engine Control Module (ECM) controls fuel pump relay operation by controlling fuel pump relay ground circuit. PCM opens ground circuit when ignition is off, and completes ground circuit when ignition is on, to provide fuel pump operation when engine is cranking or running.
Fuel pump relay receives battery voltage from the ignition switch on 2 Black/White wires. ECM controls the ground circuit on the White/Red wire. The Black/Blue wire supplies voltage to fuel pump when fuel pump relay is energized. Fuel pump relay is located on passenger's side of center console, just in front of emergency brake lever. See Fig 1 .
