Fuel Injector

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.

The fuel injector is a small elaborate solenoid. ECM sends a duration signal to injector, which in turn opens to high pressure fuel supplied by fuel pump.
