Long story short, battery got shorted to intake for .2 sec and now the car is dead. No blown fuses, all relays checked out good. Lost fuel pump and fuel guage, as well as spark. Car still cranks over. Obd2 port loses power when key is switched on. Swapped a known good paired pcm, bcm, and ignition switch and no change. Also swapped in a new interior fusebox(old one had issues to begin with). And checked all grounds and found no issues there. We are at a loss. If anyone here can help steer us in the right direction it would be greatly appreciated.

Do you not have ignition, or do you not have spark?

Do you even get priming from the fuel pump?

No prime from the pump. And no spark while cranking. I can manually turn on the fuel pump and get good pressures.
