No worries, thanks sir. :cheer: I figured the fuse got popped at some point during all the short to ground testing I'd suggested. Maybe the unplugged connector brushed up against the ICM mounting? Whatever, it's fixed! :silly:

Now heading over to their house to see why it's misfiring. They said it did it the whole way home. I let them know that on of the could was cracked, so I'll start there.

It was the cracked coil. The trusty gtc-505 showed that the wires on that coil only had 1.5-2kv compared to the others having about 5kv. A new coil fixed that.
