[QUOTE="Jdad, post: 443658, member: 22587"] I bought the jeep used about 4 years ago. It ran without a hitch til this nonsense. I don't think the coil that was in there was stock so I got one from napa . It's an eichlen branded coil. From what I've researched it doesn't make sense as to why 3 isn't providing spark and 6 is. It's the same coil with 2 terminals. The wire that feeds them is also the same. If 1 gets hot the other should to. If 1 goes out the other should as well. What am I missing here. I'm getting constant voltage and pulse signal at the connector for all. Do u know if the pcm shuts down that cylinder cause it sensed a misfire ? If so once reset should it at least spark ? [/QUOTE]
