I changed the outlets in my living room, one wall did not come back on. I then changed the breaker for that wall and still no luck. Any suggestions on trouble-shooting this problem?

I'm guessing wire may have come disconnected. Start with outlet closest to panel, that you replaced
Verify power at all breakers. Don't know if other was bad.
To determine if hot or neutral, plug extension cord into known outlet, bring female end near bad outlet. Plug meter or wiggy lead into Large prong(neutral of bad rcpticle)and other lead into hot of extension cord. Power? Neutral good(Whites), need to check reds
Or blacks, or hot color. This will help to know to look for bad white or bad hot.
But start with recpticle at either end.(connection in middle, won't stop others)on each side.
