My question is, I have to install a new abs pump module because on my left rear speed sensor I’m not getting ground from my module when I replace it. What do I have to do as far as bleeding and if there is any relearn and how to do it?

I would check the fuses first before replacing the ABS unit and check the units' grounds. here is a guide to help and the ABS system wiring diagrams so you can see which wires to test and how the system works:
