You need to get power to the magnetic clutch. Check for power to the clutch it could be bad. I usually use a jumper wire to initally charge a system. I jump a pressure switch on the filter dryer. This should always be replaced when changing a compressor.

Welcome to AF.
Always give make and model and engine and year?
Auto or manual ac?
Fuses good?
Was compresser running befor work done?

Is ac compresser relay turning on or compresser getting 12 volts to it?
If pumped down good.
It should take about 2/3 of a charge before you turn on compresser or start engine.
Enought to turn on compresser when engine is started.
How much R-134 do you have in it or have you tryed adding before starting engine?
What is the low and high side AC gauges reading now?
