I used the wiring diagrams and checked to make sure module was getting voltage from all sources,all sensors okay,pump unit has power and pump will run if you ground signal wire that comes from controler that is supose to turn on relay.Is there a way to have the module checked to make sure it is bad it sure seems like it is.
