OK, based on your responses, I've attached my gauges, and tested the pressures.

BEFORE I turned on the car with the gauges attached pressures Read:
HIGH Side = 130
Low Side = super high(off the dial scale)

AFTER turning on the compressor
High Side = ~210psi
Low side = negative (vacuum)

Robert, in your last post you said I'd likely have a blocked expansion valve with these pressure readings, however, the expansion valve is brand new??!!!

What would be your best guess at this point?

Cheers,
Greg
