Hey guys, kind of frustrated here. Could years ago I had a slow leak in my a/c system on the LX. This was right about the time I was planning on swapping the engine. I discovered it was the high pressure hose that was leaking so I swapped it out while I had everything apart.
Fast forward to now. I borrowed a vac pump and gauge set (older HF stuff), the couplers were shot so I replaced them. I also put new 134a adapters on the car was well (the car has 143a in it when I got it and worked fine). I was able to evac the system for over 30 minutes and then let it sit for an hour at it stayed near 30psi of vacuum.
I just came in from trying to put refrigerant in the system and I can't get it to take any of it. The low side gauge is reading around 90 psi, which doesn't seem right at all. The clutch on the compressor is engaging, but I can't get it to draw any in, I burned like two hours trying to troubleshoot the gauges to make sure they are actually opening and they are. What am I missing here?
ETA: I think the gauges may be messed up. Because while troubleshooting the setup, despite the gauges telling me the low side was at 90 psi, when I popped an open coupler of the low side port to verify that briefly, it pushed very little pressure out. So I am wondering if the pressure readings I am getting are confined to the hoses and it actually isn't making it into the system. No refrigerant is moving past the site glass on the gauge manifold.
