Hmm. Without videos or images or a very precise description of the problem and the mechanism, it will be hard to tell anything. The mechanism seems too simple to go wrong if its components work.
I can think of a solution that simplifies the thing: just switch the battery box and the pneumatic switch simultaneously with some simple linkage. Or maybe use the technic electric switch, it should be fairly easy to connect the lever of the pneumatic switch with the lever of the electric switch.
(BTW, although the solution posted in the previous posts is clever, I think it's a bit too clever...)
A schematic picture, I hope it's clear.... I don't have the components and the time to build it, but I think this should be possible and quick to build

first of all thank you for your attention!
I want to control the pump and the entire mechanism by IR remote control, so I have ruled out the mechanical connection to the battery box
Keep in mind that if I unplug the pump and use it manually, the system works! if I turn the motor in one direction the piston moves down, I turn the engine in reverse and the piston drops ... all while using the pump manually!
How about using the white 24 teeth gear with clutch? The motor drives the pump and the white gear, the white gear operates the pneumatic switch.
My last idea, I still have no idea what could be the problem with your solution.
