Ron, In the engine compartment I can disconnect wire #19, (from the control unit to the pump relay pin #85), and ground it and the pump will run. I reconnect it and the pump will not run. In testing it seems I get no voltage from pin #87 on the pump relay to the pump. One thing I am confused about is in the manual it states that pin #86 on the main relay goes to terminal #15 in the fuse box and pin #30/51 on the pump relay goes to terminal #30 in the fuse box. Question is what position in the fuse box is #15 and #30? I can't find any marks or lettering that indicate which is which.
