I have a 2002 jeep wrangler yj. I need help; it will not spark. I have replaced; plugs, wires, cap, rotor, modular (thing underneath cap), and coil; and it still will not create a spark. Just previosuly I had replaced the clutch in it and all that works well. However, i forgot to disconect the battery and a friend sparked the start while tightening bolts on the main. I have looked every where and everything is plugged in and and in tact. I am all out of ideas why it will not spark, motor just turns over and my coder reader comes up with no codes. Any one have any ideas?
