Your cord should be fine. If it says 115v it should work with a regular outlet then. Only issue might be is if the wires are not connected to the pump correctly. If you are sure the hot, neutral, and ground are connected correctly and it still doesn't work, then the motor is probably fried. I know you said the power cord was cut off, you might take the cover off the back of the motor to make sure that cord is connected correctly to the pump itself.
