Remanufactured Fuel Injector by AUS Injection (part#MP-10174) / Fuel Injectors

A:

For fuel injector replacement on your Nissan Sentra, you will require a socket wrench set, a torque wrench and a fuel injector kit to avoid damaging other parts while replacing. First of all, remove the negative cable from the battery. Before removing the fuel injector, it is also required to relieve the pressure from the fuel supply system. This can be done by removing the fuel pump fuse or relay, while the engine is in running condition. The engine will die out soon, consuming all the pressure inside the system. Remove also the vacuum hose from the fuel pressure regulator. The fuel injector is connected using fuel rail and fuel hoses attached to it. Using a socket wrench, remove the fuel hoses from the rail, and also disconnect the electrical connectors of the fuel injector. Now, remove the mounting bolts that keep the fuel rail in its place, so that the rail can be detached easily with injectors still on. After disconnecting the fuel rail from the intake manifold, force the injector tail slightly, so that they can be removed easily. Make sure that, you discard the O-rings that came out along with the injector. Replace these injectors with new one, which would have also been included with new O-rings. Lubricate these rings with small portion of motor oil and re-insert the injector on the fuel rail. Connect the fuel rail with the intake manifold, and tighten the mounting bolts using torque wrench. Connect the fuel hoses and the electrical connectors too. When you’re done with these steps, connect the battery cable back to the negative terminal and start the engine. As the vehicle starts, it suggests that the pressure inside the system has been regained.
