To make a long story short I took my car to valvoline yesterday to get my headlight bulb changed out thinking it may be cheaper than a $100 HID.. whatever well. the employee wasn't technical enough to change it removed my triangle fuse box behind the light with my advice after googling it. still couldn't do it. put it back together I left drove 10 feet and parked turned the key and it wouldn't crank. I turned it off for a minute then attempted to crank it by holding it it then slowly cranked and turned over. I thought weird my accessory was only one for a little bit. drove home parked the car came back out later to go get a headlight bulb and now the car won't start. won't even crank just click or doesn't. plugged in my OBD2 Scanner and it's not reading how it normally does, making me have to choose my manufacturer on my car to read the codes. codes reading Cam shaft position sensor circuit bank 1 & 2. 02 Sensor Heater, TOYOTA Igniter NO 8, I've tried jumping it. disconnecting the battery for hours to see whether the immobiliser was triggered nothing. any ideas? I've poked around that area on the drivers side that allows access to the bulb just to see whether he unplugged something. i'm fearing he pulled very hard. what do you guys think?

I've also recently changed the knock sensors. and basically every connector. only ones that were there after changing and tiding everything up was new codes 02 Sensor heater. and catalytic converter below effiency threshold 2
I don't know what to do

 

Is your battery dead? Did try jump starting it?

 

You had someone attempt to put a non hid bulb into the housing and they where also in the fuse box and messing with wiring if I am understanding correctly.
