"I understand. I'll check the gauge first. I blew out all the hoses, condensers and evaporator prior to installing. the receiver dryer or compressor is the only possible blockage. "

Even if the drier or condensers are totally plugged you should still read pressure on the high side gauge assuming your high side service port is on the compressor like they usually are. Any blockage will result in high high side pressure and low low side since the gas can't return to the compresser suction. Most likely something screwed up with the high side service port valve or Shrader valve like Rawknee said.
