The front facing power light is not turning on, even when my printer is plugged in and the switch is on.

If your printer is going too far back and there is no audible click then your y-limit is malfunctioning. This means your mechanical limit switch is either not connected or malfunctioned and should be replaced.

Your nozzle is probably jammed with a lot of debris. This happens over time because of static cling. This means the plastic spool is exposed to dust that drifts through the printers working area and tends to transport down to the extruder. This results in not burning in a complete constant line. The quickest solution would be to replace your nozzle or to clean it thoroughly.
