Test the black wire for a ground signal at all times at the pump.If you have no ground signal then this ground wire is damaged or disconnected.It usually connects around the tank area on the frame so trace it and see if you locate the issue with it needing repaired or replaced.If found to be o.k. you might try and add another ground to this wire and see if your pump then runs and operates.If the ground is o.k. let me know so we can continue.
