OK:

I'm almost there, got a new low and high pressure sensors for my 95 STS for the A/C, but it looks like there are 2 low pressure sensors? Is this true? There is one near the orifice tube and one straight back behind the engine???

thanks in advance

No, there should only be one, see this diagram, see #13, you might be thinking of #1 the low side thermister

Changed everything, Compressor, dryer, orifice tube, pressure sensors, pumped it down, charged it and still cannot get the compressor to kick on, i'm at a loss!

Check codes

Clear codes, by disconnecting the battery if the low pressure code is set, it wont start

Have you checked for power at the compressor?

I disconnected the battery for a couple hours, and when a friend of mine took the car to his garage he jumped something to get the compressor to kick in, so O know there's power
