I just installed new spark plugs, screamin demon coil pack and new wires. Tried to turn car over but made funny noise and wont stay started! I check all the wires and connections and all seem fine I need help fast!
Ohhhh good point. I almost did that with mine once.Hi Zatro,
You may have plug wires 5 and 6 reversed. They don’t follow sequence. Here’s a diagram that someone once made on the forums. Check to see that you have all the wires going to the correct coil tower, especially 5 & 6.
Yeah that doesn't look right. All the one's I've seen for the 4.0 have the low-volatge connector horizontal. Here's a link to the guys behind the SD coil:I think they sent me the wrong coil pack if you look at the pic the plug is different then from the one on AM.
+1 on that. I'm not saying you won't see any gains from the SD Coil, but most (not all) people who notice a gain probably needed to replace their plugs and wires anyways.I don't know about it being a POS, but like most add on's. the companies have a tendency to exaggerate performance gains. I also think adding quality wires, and regapping the plugs can cause some improvement on their own.
Yeah the stock plug wires aren’t really that good in these cars, and replacing old plugs who’s gap has opened up and rounded off from long service also helps quite a bit. Not sure if the SD coil actually contributes much or not, haven’t made up a test jig to compare the actual energy (measured in joules) output of the SD coil vs. the stock coil (it’s kind of a pain to do, especially when you don’t have all the equipment on hand). That’s the important number though, as far as the coil goes, and one that’s rarely given by marketeers.+1 on that. I'm not saying you won't see any gains from the SD Coil, but most (not all) people who notice a gain probably needed to replace their plugs and wires anyways.
