It sounds like you have an intermittent connection to the pump. Have a look
here for more details.
I have checked the pump it is working fine and the connections to it are clean i tried to trace the wire back to its source but none of the wires seem to match the one connected to the pump which seems to have led into that junction box on the passenger side of the car my idea of course would be to look at the relay or any other connections if I could locate it. Any ideas or suggestions.
