No brakes
2019 Corvette Stingray that I bought with front end damage has little to no brakes. I proceeded to bleed the brakes twice. I’m confident they are good in that area. I checked assist pump and it works by giving it power at the wire connection point but I get no power coming to the pump when I push the brake pedal. Have checked all fuses and relays connected to the pump. Any help or ideas would be greatly appreciated.
Thanks in advance.

Try putting the car into SERVICE mode by pressing the start button for 10 sec without pushing the brake or clutch. All systems should come on. I would expect the aux vacuum pump to run after you press the brake pedal several times to deplete any "stored vacuum." The main source of brake assist is manifold vacuum. The vacuum pump is supplemental.
Press the start button again to get back to normal.
Hope this helps.
GL and stay safe,

If the calipers were off and the Master cylinder ran dry you will have to do an abs bleed to get the brakes back to where you want them. That's also something I would check.
