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: MPV
Remove fuel pump relay, located in main fuse and relay box, next to battery. Using ohmmeter, check for continuity between relay terminals "C" and "E". See Fig 1 . Continuity should not exist. Apply battery voltage to terminal "A" and ground terminal "B". Again, check for continuity between relay terminals "C" and "E". Continuity should exist with battery voltage applied. If continuity is not as specified, replace fuel pump relay.
