I had the same problem after I installed a/c into my 2003 2.3, id have 150 psi standing pressure, the low pressure switch would never make, said F it, jumped it out ever since. Now the sucky part with pag oil is that it loves moister, and no vacuum will ever get rid of it, if your system was done dry I'd look into doing a flush and oil change.

I've thought about getting a refrigeration pressure switch for a walk in cooler since it should fit the threads on the ranger low pressure switch. And that should solve the problem.

Btw I've been giving my parts store compressor 12 volts and it's been fine. If you where looking to upgrade the orfice tube, get a thermostatic one, I put one in man it freezes me out unlike the factory one.
