Most likely something had been left unplugged but no way to tell from here. Have you run a code reader on it to see what the ECU says is wrong? That would help in diagnosing the problem.

I replaced the fuse and the car will now start but immediately starts chugging and shuts off , I’m guessing it’s the gotta be something electrical, fuel pump was fine before I replaced o2 sensor .Will try to update. I will try a code reader next and see .

Dumb "try it" suggestion, but maybe disconnect the battery for 10 minutes just to reset the ECU? Maybe the older O2 sensor had become accustomed to a bit of dirt or whatever else?

Also, pretty sure RK is a bot. As evidenced above. Do mods keep an eye out for that here? I'm new, so I don't even know who to alert yet.

So ended up just needing to let it sit for a day after replacing the efi fuse. I think it was flooded a bit from me hitting the gas pedal while trying to start the day before. Cranked it up this morning and it was sluggish at first and chugged a bit but now it’s running great. Fuse was blown from wires touching after all. 3$ fix
