No brake pedal when car running

[Rio24]

Hello Guys,  72 240Z.

I'm almost ready to drive the car I bought last year, but I can't get a brake pedal when engine running.  It feels pretty firm with engine off.   I have replaced everything except booster and lines.   I have bleed multiple times, so I'm sure of no air in system.  In my experience when a booster is bad the pedal will be harder when car started.   Any idea?

That's exactly what is means.   Doesn't really drop to the floor on its own.  Just no resistance when pressing down.  Pedal does return to the top.   I bought the car with a seized engine and got that going .   Next was the brake system need attention.   I replaced calipers pads rotors and drums ,wheel cylinders ,shoes and hardware.  Not sure what else you need.   Thanks for your time zed head

The car has been sitting for 10+ years.

I don't understand your point?   I'm here for help Zed.   You wanted details, I gave them to you.   What about the bleed screws?   They are all working properly.  I bled the system a few times.  Pressure, vacuum and manually bled just today.

I'm sorry but I thought the title of my post explains my symptom Zed head.    Everything has been replaced except lines and booster.

Is that what you call helping?  More like wasting time.  Glad I could help with your boredom sir.

Although, the part about boredom is on-point.  So, thank you for that.
