We are redoing our kitchen and just tried to reinstall the sink (single basin/single drain) and I hooked it up exactly like it was before and now it doesn't seem to want to drain past the p trap. I've completely taken apart every pipe and there is no clog and I've tried plunging it with no success. I'm out of ideas and quite frustrated. Any help would be wonderful. I will tried to upload pictures if that helps

It's actually possible that while you had it open the stuff in the pipe downstream solidified.

I would suggest snaking starting after the p-trap.

I've taken it apart past the p trap and there is no clog at least not until it goes out to the street. Plus it fills up and overflows once it hits the p trap/ garbage disposal area.

Check the J pipe it should not go too far inside the wall it will cause blockage see the Image below, Good Luck.
