Coil pack melted

Hi all. I was changing my plugs and coil packs and noticed that one of my coil packs was melted, I eventually got all the pieces of plastic and metal out and then pulled my spark plug out and it looked bad. It was black and covered in soot. I also noticed that the threads at the bottom were gone and also the little metal part that sparks was also gone. I tried putting in a new plug just to see if the threads would catch and it would not start. What would cause that and what all issues am I facing? Should I just cut my losses and get another motor or how should I go about fixing it. Thanks

 

Been there, 4.6 3 valve Ford is notorious. You need a helicoil

Probably look for better quality. That is just an example.
Best case is thread repair, worst is head replacement. Most of the time they can be saved

 

Wow, first time I've seen that. Glad @Tundra family was able to help so quickly.

Probably a really dumb question, but how well did it run with a dead cylinder? Did you have a code?

 

Mr badwrench it was running fine well I say that because at the time it happened my wife was driving and I was outta town working but she said it was running fine and I had not checked for codes because it had been running so good. At the time It quit running she said it just kinda died and said it tinked a few times which now I assume was the bottom part of the sparkplug. But initially when I put the ODB reader on it it came up that fuel pump was out so I dropped the gas tank and changed it but now it's giving a faulty igniter code starting with the plug that's fried.
