Hello,
I am very frustrated at this point. I have an 02 blazer 112000 miles, started arcing from the coil pack to the mounting bracket. I replaced coilpack, wires, cap & rotor, and plugs. Still arcing from same place, it would start and idle fine under any load it would arc like crazy at the coil pack. then it sat a year, now still arcing but wont start at all now!! Help please
