How to Install an Integra Fuel Injector

The Honda Integra was a compact sports car manufactured from 1985 to 2007. The last generation of the Integra includes the 2002 through 2007 model years, which Honda sold as the Acura RSX in the United States. A late-model Integra has a four-cylinder, 2.0-liter engine with multi-port fuel injection. Each fuel injector sends fuel to a cylinder in a specific sequence. The installation of the fuel injectors also requires you to relieve the pressure in the fuel system.

Instructions

1

Remove the cable from negative battery terminal with a socket wrench. Detach the kick panel under the dashboard and remove the fuel pump relay from the fuse box. Start the engine and allow it to stall to relieve the pressure in the fuel system. Open the fuel filler cap to relieve the pressure in the fuel tank. Replace the fuel pump relay, and fasten the kick panel. Close the fuel filler cap.

2

Disconnect the cover on the intake manifold with a socket wrench, if your vehicle is so equipped. Detach the electrical connectors from the fuel injectors. Release the quick-connect fittings on the fuel line, and detach the fuel line from the fuel rail. Disconnect the fuel line and vacuum hose on the fuel pressure regulator.

3

Remove the mounting nuts for the fuel rail with a socket wrench, and detach the fuel rail from the intake manifold. Release the retaining clip for the fuel injector. Pull the fuel injector up as you rock it from side to side to remove it from the injector bore. Discard the O-rings on the fuel injector.

4

Coat the new O-rings with a thin layer of gasoline, and mount them to the new fuel injectors. Install the fuel injectors to the fuel rail, and attach the retaining clips. Mount the fuel rail to the intake manifold, so the injectors fit into the injector bases. Fasten the mounting nuts for the fuel rail, and tighten them to 16 foot-pounds with a torque wrench.

5

Attach the fuel line to the fuel rail, and connect the quick-connect fittings. Install the fuel line and vacuum hose to the fuel pressure regulator. Attach the electrical connectors to the fuel injectors. Replace the cover for the intake manifold with a socket wrench, if your vehicle is so equipped.

6

Connect the cable to the negative battery terminal with a socket wrench. Start the engine and allow it to idle for two minutes. Turn the engine off and correct any fuel leaks.
