This code indicates that a part of the EVAP control system is no longer fuctioning correctly. Thus, I don't see how it is related to the pump running. (Not saying it isn't possible)
Have you done the following? Check to make sure gas cap is good? Inspect the EVAP system to make sure there are no cuts or holes in the hoses? Any disconnected hoses near or around the purge solenoid? Check purge solenoid?
