I know what you are talking about, the coil pack is burnt on the side of the coil, it's cracked and burnt and cooked, probably smells like an electrical fire. These guys that are trying to help you by saying " I have never heard of a coil pack burning up, it's your spark plugs" or what ever they are saying just shows they are not technicians and probably shotgun parts at cars and hope they fixed it. I have a 2014 Cruze in my shop right now for the exact same problem. We have not figured it out yet but as soon as we do I will post the fix for you and hopefully that will helps.

I have a 2011 Cruze 1.4L in my shop now with the same issue. There is a short to power at the IGN coil #1 circuit (terminal D of the Ign coil connector) coming from the ECM connector. Somehow power is travelling through the ECM connector (Through the plastic??) I haven't determined the fix just yet, only the problem. Hope this helps.

Have you fix the problem? If not look at my discussion that I posted.

Check my previous message.

The shorts are usually due to corrosion from coolant wicking up the harness through a failed sensor or t-stat heater. Sometimes it's carbon buildup from burned connections due to high resistance in connnector(less common)

I'm still working on a fix here, removing the pins and cleaning the connector doesn't seem to help. THoughts?

Back the ign1 terminal out of the ECM connector, see if your short to power goes away. If it does you either need a new ECM or just need to clean better(likely taking apart the connector body and cleaning in between the female terminals) if the short doesn't disappear you have a physical short through the insulation, just run a new wire from the ECM to coil

no amount of cleaning could stop the short. This was ridiculous. I swapped the X3 and X2 connectors (I had to shave a bit of plastic off so the connectors would swap.) Every wire transferred over easily and X3 doesn't use pins 1 or 2 which is where the short was located.

I'm having the same issue with my son's 2014 1.4T. New plugs. New ignition coil x2. #1 misfire and has blowed the 2nd coil and keeps blowing the 15amp injector fuse. Could a bad injector be the problem? I've also cleaned and reconnected all the ground wires I could find.

Did you watch the video I posted. This is probably your problem

Did you figure out the problem? I was driving to work and my car started missing bought a coil pack, put it in and totally burned cylinder 1’s coil. (It melted and came apart when I removed it) I thought I had gotten a bad coil pack so I returned it and got it replaced. again the second coil pack started shooting the fuse. I thought maybe it was a bad (autozone) product and replaced it with a different brand same problem third time out now I am at a total loss and have no clue which way to go.

Yes, there have been three different posts with the fix. One of them is a video.
