Sam, i'm not saying that what i put out there is THE message! I doubt seriously that my compressor is the problem! However, no matter what I do, it does not turn on, period: the clutch does not move! I cannot put in freon.

But, the troubleshooting material does lead me to consider that I am not getting battery power to the high pressure sensor, nor to the low pressure sensor. I DO get power to the blue/grey wire in relay connection. And knowing from the reading the circuits that the same blue/gray wire that comes from the relay goes to the high pressure sensor, i probably have a problem somewhere in between.

I can jump the low pressure sensor connector all i want and still won't turn on that compressor. As far as I have studied and read other peoples' contribution on the subject, if my compressor does not turn on, there is no use trying to put in freon, oil, sealant, etc. And I really doubt that my compressor is bad.
