How to Replace a Fuel Injector in a Chevy Camaroby Contributor
The Chevy Camaro mixes fuel and air under pressure with a fuel injector. This function was previously performed passively by carburetors until the late 1980s. One advantage of fuel injectors is the programmable firmware that allows the fuel injector to handle different fuels. A fuel injector is made up of only the nozzle and valve; it still requires the pump to pressurize the fuel.
Determine which fuel injector your Chevy Camaro will need. This depends not only on the make and model, but also the engine size. Models made from 1967 to 1969 were available in a variety of engine sizes including 3.8L, 4.0L, 4.9L, 5.4L, 5.7L, 6.5L, 6.6L and 7.0L.
Look at engine sizes for additional Camaro models. The second generation Camaro covers the years 1970 to 1981 and was offered with 3.8L, 4.1L, 5.7L, 6.5L, 6.6L and 7.4L engines. The third generation was made from 1982 to 1992 and came with 2.5L, 2.8L, 3.1L, 5.0L and 5.7L engines. Models made from 1993 to 2002 had the option of a 3.3L, 3.8L or 5.7L engine.
Disconnect the negative battery cable with a socket wrench and relieve the fuel system pressure. Remove the fuel send and return lines from the fuel rail and detach the fuel injector electrical connectors.
Detach the vacuum hose from the fuel pressure regulator, unplug the manifold absolute pressure sensor electrical connector and disconnect the vacuum line from the fuel pipe bundle.
Remove the fuel injector harness fasteners and the mounting bolts for the fuel rail with a socket wrench. Release the retainer clips for the fuel injectors and remove the fuel injectors. Discard the old O-rings.
Install the new fuel injectors by reversing the removal procedure. Coat the injector O-rings with clean engine oil prior to installation. Use a torque wrench to tighten the mounting bolts for the fuel rail to 89 inch pounds.
