You can’t determine what fluid is on the plug to make it wet? Coolant? Fuel? Oil?

Old car. No fuel filter after the in-tank pump. Junk ends up in the fuel rail down at #1. Bet you have a clogged fuel injector, or at least junk in the rail down there. Resulting lean condition would explain the toasted plug.

Any history of fuel line leaks due to corrosion?

Based on the codes he pulled (one was for ignition coil on that cylinder) I would guess he messed something up when replacing the plugs and coils.
The wet cylinder sure sounds like unburned gas. (That coil wasn’t firing but the injector was still working. )
He needs to confirm what that wetness is.
The compression test would help to tell if there is any cylinder or piston damage.

As far as the burned off end of that plug. I would like to see a picture of it.

This is about an LNF SS , so direct injection ergo the fuel rail theory is questionable.

Maybe, #1 was not torqued down enough.

Just another 2 cents, is it possible there is an active code in the computer shutting down the cylinder? maybe record the codes and try clearing them. My smart used to do that and the cylinder wouldnt run until I reset the code even after replacing the plug and coil...

OK..... Just came in from checking Spark.... I only checked the #1 since all the others were dry, I reset the ECU cleaned and regapped the original plugs and started it up..... Still Missing I did notice When I revved it up it seemed to sound like it's power was still there and leveled out but when I let it idle it was pretty rough? I pulled the plugs #1 soaking wet with Gas and the other 3 normal..... Looked down into all the holes #1 Soaking Wet???? all the others normal !Damn I don't know a thing about Turbochargers so that's one reason I'm Paranoid! I don't know what to think? Any Suggestions or ideas with the new info if anything comes to mind..... Please Let Me Know! I Thank You! I'm Still Freaked Out!!!! But somehow I'm beginning to think it's FUEL Related? Seems like #1 is getting so much fuel dumped into it? Or the spark plug was sparking but maybe not Properly? Since I didn't check the other 3? Seemed like a good spark to me? Thanks Again, Tony
