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
Disconnect fuel pump harness connector. For location, see FUEL PUMP HARNESS CONNECTOR LOCATIONS table. On Frontier 2.4L, measure resistance between fuel pump connector terminals No. 5 and 6. See Fig 1. On Maxima and Sentra, measure resistance between fuel pump connector terminals No. 1 and 3. See Fig 2. On all other models, measure resistance between fuel pump 2-pin connector terminals See Fig 3. On all models except Murano and 350Z, resistance should be 0.2-5.0 ohms at 77°F (25°C). On Murano and 350Z, resistance should be approximately 1.0 ohms at 77°F (25°C). Replace fuel pump, if resistance is not as specified.
| Application | Location |
