You “have power” to outlets for the circuit you replaced.
What voltage do you have? If you “have power”, how do you know?
Sounds like you might have a voltage drop somewhere between panel and the outlets. Disconnect power when you aren’t around, good chance for a fire. Post voltages at start of run. Disconnect first receptacle, check voltage, and post here again.
If you don’t have a meter. Change the first outlet in the run, and leave the rest disconnected and test with an appliance. If it won’t run, you have a problem in the line from the panel, or where the breaker mounts, etc.
If you aren’t 100% sure of what you can/can’t do inside the panel, call an electrician, it might be your life.
