WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2000 Nissan Xterra, 2000 Nissan Sentra, 2000 Nissan Quest, 2000 Nissan Pathfinder, and 2000 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect fuel pump harness connector. For location, see FUEL PUMP HARNESS CONNECTOR LOCATIONS table. On Frontier and Xterra 4-cylinder models, measure resistance between fuel pump connector terminals P1 and P2. See Fig 1. On Maxima and Sentra, measure resistance between fuel pump connector terminals No. 1 and 3. See Fig 2. On Quest, measure resistance between fuel pump connector terminals No. 2 and 3. See Fig 3. On all models except Frontier and Xterra 4-cylinder models, Maxima, Quest and Sentra, measure resistance between fuel pump 2-pin connector terminals. On all models, resistance should be 0.2-5.0 ohms at 77°F (25°C). Replace fuel pump, if resistance is not as specified.
