Default Need help!!

Car is a 2006 GS 430, Got into a small fender bender front end collison.
First problem: after the wreck power stays on unless I disconnect the neg. battery cable.
I have looked all over, cannot find any damaged or pinched wires.
I could still move the car in and out of the garage when I needed it out of the way.
I dug into it one day taking off damaged parts, replaced the serp belt tensioner.
I reoved the radiator support and trans cooler, THIS IS WHERE I GOOFED UP.
I needed to move the car off my lift at this point to work on something else. I wasnt thinking and moved the car over one bay in my garage and pissed alot of trans fluid out. This made the car very unhappy and wouldnt crank after this.
I was able to refill the trans fluid I spilled out, but still the car wont crank.
I have the immobilzer code b2799, along with VSC, and VGRS.

ECU doesnt read my key fobs. I have tried to relearn them with 0 luck.
ANY HELP would be great!!!
TIA.

Did you test the starter for power with a test light, that way you can factor out a lot of issues and go down the line of easy things to diagnose. If theres no power or trigger wire to the starter then you can trace it to the fuse relay

You said the car stays running until you disconnect the power from the battery. Maybe its possible that the main fuse/fusible link popped as you disconnected. The fusible is the main cut off for the entire electrical system, its possible and I have seen some members have happen to them that it partially breaks. So certain electrical will stay running but the main stuff is off line.

If you have a lift it shouldnt be to difficult to probe the start, it will atleast give you a starting point of diagnosis. You can also test for power to the starter at the starter relay in the engine fuse box. You want to check for power, and a power on signal, so you will need to have someone inside the car with the key fob and attempt to start the vehicle.

Which fuse box contains the main power supply?
Power stays on, not the engine.

Its not called a fuse, but fusible link. Its basically the main fuse for your whole car. Its a pain to get access to it
