mean green cobra

I'm building a project car. The car starts butt I can't keep it running because I don't have a belt in it yet or my a/c delete kit yet . Does ne one know if u are able to bleed the brakes with the key turned forward and someone pumping the brakes or does the car have to be running . Thanks for your help

No vehicle requires you to have it on to bleed brakes! Not to be a dick but if you didn't know that do you really think you should be bleeding your own brakes?

Only if he promises to post the video of his first post bleed test drive.
