Want to get some opinions on this issue. Recently bought the car and knew the AC wasn't working. Hooked the gauges up and was 0 pressure. Gave it a charge but still isn't bowing cold. Static pressure is about 55 on both sides. Turn the engine on and turn the AC on max and the low pressure side drops to 30 but the high side only goes up to around 70ish. This sounds like a compressor issue? Being mid-engined its not that easy to visualize the compressor during all of this. Are there and other tests that I can do to get to the bottom of this. Anything electrical to test? Pressure cut off switch?

I checked around with a black light to look for leaks but none that I could see. I assume there are probably some leaks somewhere since it was at 0 or the system was evacuated at some point but there is another definitely another issue going on since the high side pressure isn't going up.
