See my profile, Imma CJ kinda guy......I like carburators.

The reason the injectors have power, is they Open and Close.............Or adjust.

The adjustment is made by the computer.

The computer takes in all of the information that the sensors gather, and "DECIDES" how much fuel to inject into the cylinders.


This process makes the injectors adjust alot and fast......The computer is trying to make the engine run as efficiently as possible many, many times a second.

Is that what you wanted to know, or were you wanting to know something about testing the injector system?

If so you might give us a little more info, on what you specifically need.

Your Turn,
