and yet I am still trying to figure this out

I went out and warmed you the for like 5 minutes. I had the radio on and the A/C off. I put it in gear and not even 10 ft from the driveway, it went black. like no dash light(s), no headlight(s), nothing. I even chequed the battery connection(s) and they were like good ...

the only code that I had for the car is the upstream O2 sensor and I have the replacement ( just didn't have the time yet to like install it and was planning for the weekend )

the question is, what am I suppose to look for besides a blown fuse ... ?

 

welcome to the forum. timing belt, checked the battery connections means you took them off and cleaned both the poles and clamps. check battery voltage or short battery, and yes fuse.
