I have a 255 lph Walbro pump. It's out of the car and i need to verify that it works. I applied 12 volts and it clicks but it doesn't make any other noise. Is it shot? Should it make a whirring noise like it's pumping or will it only make that noise when submerged?

Update. Pump is sold and is on it's way into a car as we speak. I'll update this thread if i have to a) return the money and accept a faulty pump in return or b) keep the money and let DSO know that good pumps do not "whir" when tested outside of a tank.
