Your said - " so I changed the relays, checked fuses, changed ecu and bcm (paired ), still won’t crank over " :confused:
" I turn ignition on I get dash lights "
That is were your problem is !
Did you actually program in the Keys into the BCM ?
BCM / Immobiliser doesn't recognise the Keys, so It wont crank over.

When you got the pcm and bcm out of the other car did you also get the keys as these are linked together, was the pcm out of another vx l67 or was it out of a ecotec vx.

Have you retried your original pcm and bcm to see if it will start.

Your original bcm should have a series number on it, like was mentioned above if its not out of the same vehicle serries as yours it wont have the correct wiring set up.
Ok thanks so if the new ecu has same series number it should work another question why dose trac off go off by itself then I have no control over it and all of a sudden my obd plug isn’t working can’t fault code check it

Yes I tried that but my computer has that burnt electrical smell to it is there anyway to check the ecu if it powering up or not
