Advice - Compressor Not Engaging

Thought I would close this thread out with a final update. After a bunch of torture, I replaced the low pressure switch, which also did nothing. But what did was the stupid fact that the conversion fitting I put on were setup in a way that the 134A quick connects were not engaging the Schrader valve. Once I eliminate them and restore the old connections, I was able to pull a vacuum that held, and charge right up w/o issue. Clutch engaged, very cold, seems to be working well so far.

Thanks again for everyones input on trying to get this working.
