Don't know if it goes through a resistor. Just read the manual that says the injectors are fired by grounding to earth, and that the wiring is not polarity dependent, ie either wire can go to either terminal on the injector. Unfortunately, I am electrically challenged. (I can, however turn on a lightswitch and operate a radio and a television). Regarding the ohm check....should this be done with the ignition on or off, or should it be done with the engine running? I was thinking that if I disconnect the fuel pump wire so that the engine cannor start, possibly turning it over and listening to the injectors would tell me if they are clicking? Or might this be too diffucult to hear? Thanks for any and all suggestions on how to check this out.
