I have a light switch connected to a wall outlet. The light switch turns the wall outlet on and off. I just stopped working. I have replaced both the switch and wall outlet, but there is no power going to the switch or the wall outlet. Any thoughts as how to fix this problem?

There is most likely a loose wire connection someplace in the circuit ahead of the switch that needs to be found and repaired.

Did you confirm power to the switch? Check the breaker too.
