The function of the injectors is to spray fuel into the cylinders in the correct spray patterns. This happens sequentially.

The injectors are located under the intake manifold.

The engine control module (ECM) controls the injectors by grounding the valves in pulses.

The injectors can be diagnosed by the engine control module (ECM) and can be activated.
