poor ground on coil packs?
I had posted a couple of weeks ago about my 97 Elantra where the timing belt broke and we replaced the head and now it won't start. We went to work on some of beppomarx's helpful suggestions, but while the spark plug wires were out, it sounded exactly the same while cranking as if they were in.
Assuming we used our Radio Shack electrical tester correctly, The coil packs didn't read any voltage coming out of the wire plugs. Using our Radio Shack voltage tester, I read 12V from the black/white stripe wire going into the coil pack when grounded to the negative battery terminal. I only read one volt when grounding to the browning wire going into the coil pack, but the same thing when grounded to the third wire.
I took the pack to the two major stores in town, and neither could test them, but one guy said it looked like it wasn't grounding properly, and that it was grounding out of the side of the coils, into the metal bracket that holds it. There is ashy discoloring to support his guess. Does the coil pack use one of the other two wires to ground, or does it ground to the cylinder head?
Does this sound like something wrong with just the coil packs, or might there be a problem elsewhere in the wiring? Thanks again for the help.
