    Are you saying that the spark plug is not igniting or what do you mean by "power / pulse"? Could be your spark plugs or wires or distributor. Need more information.

    verify if you have no power or no ground at faulty injector. most mitsu's use a ground controlled circuit to pulse the injector. I.E. ignition on, power all the time at injector, engine running(or cranking) ground side of injector is pulsed by the PCM. Specify which model and engine you have
