Why is my truck running badly?

Anyone know why It’s running so bad??

It’s my project truck, I’m building a rock crawler out of it and LS swapping it but I need it to run for now so I can move it in and out of the garage until I’m ready for the LS. Any help would be appreciated.

Here’s what happened:

It ran fine a few days ago until I was rerouting some wiring. I unplugged the ignition cable on the steering column to zip tie it out of the way and one of the wires sparked off the steering column . (Yes I’m an idiot for not taking the ground off of the battery)
when that happened it blew a fuse so I plugged the ignition back in and replaced the fuse.
Right after this I went to start it and when I turned the key everything turned on, relays, fuel pump, etc. but it wouldn’t crank and there was no power to the ignition system so it wouldn’t start.
(See first video)
After this I unhooked the ground wire from the battery and waited a minute then hooked it back up. Now it starts but runs like crap. (See second and third video)

(Also, the knocking you hear isn’t new, I know the motor is junk)

What could be the problem??
