How to Replace a Fuel Injector in a Honda Accord

The fuel injector in a Honda Accord mixes fuel with air under pressure and rendered carburetors obsolete during the late 1980s. A fuel injector has programmable firmware that allows the same hardware to handle different fuels. The fuel injector consists only of a nozzle and valve; it still requires a pump to deliver fuel into the engine.

Instructions

1

Determine which fuel injector your Honda Accord will need. This depends not only on the make and model, but also the engine size. Models made from 1976 to 1985 have a 1.6L or 1.8L engine and 1986 to 1989 models have a 2.0L engine. Models built from 1990 to 1993 are equipped with a 2.2L engine. Models made from 1994 to 1997 have a 2.2L or a 2.7L engine.

2

Disconnect the negative battery cable with a socket wrench and relieve the fuel system pressure. Remove any components needed to gain access to the fuel rail.

3

Unfasten the mounting bolts for the fuel rail with a socket wrench and disconnect the fuel rail. Carefully remove the fuel injectors from the intake manifold. Discard the old cushion rings, O-rings and seal rings.

4

Install the new fuel injectors by reversing the removal procedure. Lubricate the injector O-ring seals with clean engine oil prior to installation. Align the center line on the injector with the mark on the fuel rail when placing them into the fuel rail.

5

Turn the ignition on to pressurize the fuel system and start the engine to check for fuel leaks.
