01 Flashing light then random codes after sparkplug install...

01 xj 233,000
I should have posted this week's ago when the car was in my possession and was fresh in my brain . I'm hoping it will spark some good conversation or when I post the fix (hopefully) help somebody else out... I had a flashing engine light that happened once and went away after restarting car. Naively I went out of town 3 weeks later with no issues and it happened again to not go away. It was basically running a little rough like in 5 cyclinders...Took it too a small towns mechanic and he said it was a #6 misfire .. tested the sparkplug no spark. Put a new spark plug in... now is where it gets strange ... absolutely no start and is throwing cps code that it didn't have before.
Dude ordered a new cps didn't change a thing. The thing under the cps was a little wobbly but I'm not sure if it was that bad or causing the issue... anyway it also randomly threw a 700 something something transmission code randomly at the end to throw even more confusion
I insisted maybe the pins were damaged from putting the coil pack on with the connector still connected but he checked it with a mirror and I'm hoping would test it some otherwise down the line :/
