micheal-look into the plug boots. there should be a small clip that pushes onto the plug tip you see. this is what it is supposed to be. take a plug and experiment. you'll feel the threads going into and out of the clip. if no clips, those are the wrong wires.

on the injection system, that signal at the injector is tough to see with a test light. it's pretty low voltage. try an led on 1 that works and see how it triggers. if that works, then go to the dead ones. then go to the intake and make sure all the ends are on the ground wires and the connections are clean and tight. if ok, then go the ecu with the led and check pins 13,14,21 and 22. inputs from the trigger pts. if ok, check pins 4(4 and 8) and 6(2 and 7) outputs. if no, check pins 3 and 5-other injectors-to verify. all this is done with the car running, if possible, or cranking. if the ecu has power and ground-it does, 1/2 the car runs, all 4 inputs from the trigger pts are there and the grounds from the dead cylinder injectors are ok, this means either the harness is broken or the ecu is. keep us posted, please. good luck, chuck.
