2780a that is mean there is no 5v output from smart because 5v short it to ground

First thing
disconnect bumper antenna and check resistance
it should be 1 or 10 mega ohm if show 1 or 3 ohm that is mean bumper antenna short it disconnected and never connected it well burn the ic inside the a smart control again if U replace new one

Also check resistens between ground and 5v of start push button if show you with ohm replaced and if with mega it's ok

Open the smart control and check the small IC upper left of processor of smart control if burned
1 . if burn you well see small notsh on the surface of ic
2 . Let smart control connected and let some one push start button more than once and check the temperature of ic with your thumb
If temperature so high that is mean ic burned

If every thing is ok then your problem in line
Line: it is a wire connect all of component of smart unit ,ID box ,steering lock and BCM if there is open or short on line wire you well get also P2784 and P278A

Good luck

remove contector from push switch, smart key and door control receiver. Check resistance between pin29 and pin 17 of smart key big connector.
It should be more than 10k if it's ok then Replace your push switch. Don't connect door receiver. Now try to start with key logo side touches the push button.
