Compressor working when I jump it.
But not working when I connect back to system even after I change the A/C relay.

It may be that your charge is low and the low pressure switch (a safety switch) is not allowing the circuit to complete.

Here are some guides from "repair guides" at the top right of our pages. Here is the A/C guides that may help you understand the workings better:
