how did you charge the system with the new compressor unable to run ?

recheck fuses all...check clutch coil resistance/voltage to clutch..check that the diode there is not shorted out ..connectors os connected..

Did you check for power across the compressor connector or to a known good ground?

i finally got power to the compressor. something is telling the relay not to give power to the compressor. is it the pcm?
