You might want to verify, but I "think" the C4025 number you gave me was for your cartridge filter, not the pump.

Just follow the power cord to the back of the pump and see if there is any type of switch that you may be able to activate. Since your pump is wired to a timer, then you may want to see if the timer itself is actually "on time". When the power went out, it may have stopped the timer at a certain point. Also, maybe your timer has a manual override lever which will allow you to try and turn in on at any time? Since you don't have a multimeter or tester to check voltage, you can only try and follow the power lines or conduit from the timer back to the circuit panel. With a house almost 20 years old, you may have more than one circuit panel to check, but always be careful when following those lines back to the breakers and never touch anything directly with your fingers. Safety first! If you find a model number for the pump itself, please let us know. Maybe it will help.
