Where do I locate the central port injection on my car?

Answer by  McCheese (1248)

Pop the trunk, locate the battery, and follow the fuel power line to the central port injector. The fuel power line is always green. This is uniform on every make and model, except for some vehicles explicitly built for the military. If you have an older car, the wires tend to gunk up, so bring a wet cloth to clean.

On early multi-port fuel injection engines some manufacturers utilized an extra injector in the upper plenum of the intake manifold to assist in cold starts. The plenum is the uppermost, open chamber of the intake and will look like a sensor with a small tube (fuel) and wires.

The central port injector is on top of the motor. It will look like the carborator and under the air filter.

It would help if you said what kind of car you had. I would try following the fuel line on top of the engine. That is where it should end.

The central port injection is going to be located on the fuel rail and it will run accross the top of the motor. It is easy to find once you know where you are looking for it.

The injector is in the center of the intake manifold on the 4.3 engine and hidden inside the split plenum manifold.

The central port injection supports the engine with gas. So it's good, to start your search on the top of your engine.

The central port injection is a rail that brings the fuel to the injectors. It will have the inlet and return fuel line attached to it near the throttle body.
