Ok guys I am having some major issues with these coil packs. The other day one of them just melted. The truck died and I got a 2317 code. So I installed a new one and the same thing happened on the same coil. The truck died while driving down the freeway and I got the same code. Anybody know whats going on? Here’s pics of the new melted coil pack.
It happened again!!!

Just curious after the first time did you pull the plugs on that cylinder to check them for damage?

I'm not familiar with the Hemi setup, but does the plug wire go there? Is it possibly a plug wire problem thats messing up the coil pack?

if its under warranty, have it fixed by them. ask matt, the last thing you need is for your engine bay to flame up on ya
good point, but I'd check your ground straps from the valve cover to the head first.
Great info guys! Ok to answer a few questions… I did pull the plug and is in great shape. I changed them just in case anyways though. I thought about the arc1 also hemifever. I checked all the wires and connectors and they are good to go. I switched the bad coil and shorty plug over to another cylinder and the good coil and shorty plug to the bad cylinder. Well the good coil started to melt. So I know its cylinder 6. I also got a misfire code on cylinder 6 and I always get the 2317 code. It back fires and shakes a lot. I’m assuming it’s because the cylinder is not doing what it’s supposed to do. I’m not sure if I checked all the grounding straps but I did what I could. It was towed to a dealership. Just waiting for them to open in the morning. I will keep you guys informed.

you definatly have a wireing problem. you have constant power applyed to the coil someplace. because the coil is getting continuios voltage and having current flowing all the time and overheating the coil. im not sure if the hemi's are ground switched or power switched. (i would assume power) you need to find the source, i would figure out what wire it is off of the PCM, disconnect that plug and check there for voltage. and see if you can get it to change with the key on/off. and if you get a constant voltage on that wire (with it disconnected form the PCM) you will know there is a problem in the wireing someplace if there is nothing connect it back to the PCM, and test at the connector. (for the coil) and if you have countinious voltage there your issue will be in the PCM. because if i remember right the power for the coils comes straigt off the PCM to the coils. (nothing in between) so that is what i would check.

I don't suppose the fuel injector could be screwed up throwing too much fuel in there?
He says its back firing which would also lead me to believe his motor is out of time or that cylinder is firing out of time. I'd go further back on the system and find out where the timing is being thrown off.
