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.
