Jeep 4.0 just turns over after spark plug change
Been lurking for some time, so anyway.
Have a 2001 XJ, was time for plugs so I gapped and put in new NGK plugs. Changed plugs numerous times so no big deal. Put coil pack back on, clicked wire harness back on. Reconnected battery, fires right up, sounded fine. Was letting it idle a bit. Then it turned off and then just turns over and won't restart. Scanned for codes, nothing.
Clueless because clearly I missed something, but I've changel plugs before, just not in this Jeep.

I assume no spark, it just strated again and then died after 30 seconds. I had to take my girlfriend to the clinic since she just broke her finger. So luckily the Jk runs fine.
I am going to take the coil pack off check the plugs again and inspect the coil pack when I get back. I will update if I find anything, unless of course anyone else has suggestuons.
Also I might be on mars, never had issues changing plugs lol.

Did you recheck your work to make sure everything is seated properly? After changing dist cap once it ran rough after, come to find the center terminal would pop right out.. I know your dist'less but its just for relevance!

Wasn't my fault, dude at auto zone pulled wrong plugs than he was supposed to. They were a tad too short for combustion. I was at fault for not double cheking and at quick glance without comparing they looked similar. Good thing they weren't too long, however it's fixed and I feel like a tool
