Waking up ABC tandem pump. Oxygen?

So I have yet another question for you ABC experts out there. I was able to run the rodeo today with no problems, actually twice. Then I turned the car off and restarted and then I get nearly 0 bar of pressure. If I puff some air into the resevoir tank then the pump wakes up and goes up to about 170 bar. So my question is should the pressure read higher and why can't the pump build up the pressure itself? Does this mean my pump is weak and can only hold pressure do you think? During the rodeo the pressure read between 160-180 bar.
