From the noise and A/C output, it does sound low.
The green liquid coming from the evap sounds like condensate with refrigerant dye mixed in, indicating a leaking evap. Has anyone added dye?
Static pressure will be as per the refrigerant's temp/pressure curve until they system is virtually empty (i.e., as long as there is any refrigerant in a liquid state.) I'm oversimplifying, but in ambient temp between 80 and 100F, the static pressure of R-134awill be close (numerically) in psi to the temp in degrees F. Pure coincidence. (Don't forget, with engine running or run recently "ambient" is well above the air temp 10 ft from the car.)
The death kit gauge is useless. And the info they're giving you is with the comp running. But it seems your refrig. is so low it won't turn on, or may actually turn on for a split second until the LPCO, on the suction side, shuts it down.
