Hello All been back on camaro this morning, on Diag i can only talk to BCM which has a list of faults all relating that it can not communicate with any other modules, today i disconnected seat module incase they were shutting down the can or lin bus lines no luck there. disconnected rear RKA module i think its called in drivers side rear boot,no joy there still no power up of ignition systems.
Checked again all supply feeds in fuse box front and rear all good there even put a jumper wire on to engine ECU supply fuse still no power up.. I disconnected a module to the rear of the glove box and the front passenger window dropped down on its own and now won't go back up.. so still looking for any advice

I am still having grief with it and looking for some more advice if you help me with that please.

So far with the diagram on the push start switch I have a good Earth but only 8.1volts on the positive supply I have 4.8volts on the side light wire which I think is correct but unsure the 8.1 volts is incorrect, so my question is do you know if it should have a full 12 v supply and if so do you know where is comes from?

I have bridged out the RKA module in the boot from a 12v main supply and I have bridged that to the Ingition wire to back feed, when I do that I just get the engine EML light on and my diagnostics will communicate with all things on the vehicle.

There are some things it won't communicate with but it might not have the module on the car.
I have enclosed some pictures of my diagnostics screen so you can see the fault codes showing.
With the bridge in place I still have no windows/wipers/heater/hvac and still no crank.
My Diag tells me I have no accessory ignition either

On Diag I can comm with the cluster and test all led on there but the pointers won't work.

The fault codes I have pulled out are in the key access system
B144B-01

In the serial gate way module (where ever that is or what it is do you know please)
B101D-36
B101E-43
