New member here. Not sure if this is the right place to post, so forgive me 2013 Cruze LT 1.4 with 114k miles. Problem started with engine running rough/misfiring Had misfire cly#1 and multi misfire codes. I pulled off the coil pack to check for spark. I put I put Test wires with alligator clips from ground to each of the boots 2-4, so not to burn up the module. I used a test Light on #1. As I cranked the engine I found that I had no spark coming from #1 coil. So we changed out the coil pack. While we were in there we changed out the spark plugs with the same type. AC Delco with a gap of .027ish. Car ran great, drove around the the neighborhood. Next day had another problem with cooling fan ( found out that it has a low - med and high speed fan. Only had high all this time. Own the car for about 1-1/2 now. Who knew. Anyway replaced the fan. All good ) However before checking out the fan. Once I shut off the engine I here a sizzling noice and seen smoke coming from under the coil pack cover. Disconnected the battery just in case. Found out the the #1 coil burnt through the side of the coil pack. Local shop side to buy it from the dealer because they had problems with aftermarket ones. Well we went ahead and had the coil warranty out. Everything running good again. The next day the light came one and had injector and misfire codes. Got it home. Went to start and cranked but no start. Found No power to coil and injectors. Blown fuse for the injectors and coil. Coil pack was causing the fuse to blow. Pulled coil pack off. Found that the coil at #1 on the end was blown out big time. Looked at the OE coil More closely . Looked to have a small burn out on #1 also. The springs are all the same length. No corrosion on coil connector or at the computer. Got money back on coil and they said could be a bad batch of coils. Going to change out the #1 plug just in case it’s bad causing high resistance. On the next coil we put on I’m going to stretch the springs to make sure they are touching. However before we buy a new coil from the dealer does anyone have any input on this. As I’m sure the dealer wouldn’t warranty the coil out like o’Reilly’s did. Sorry so long but more information there is the easer it is to figure out. Thanks.
