GMC box truck stall, and power steering leak 

Box truck would not start at first so cleaned battery terminals and power steering leak was the pressure hose pump to hydro booster . Note a little leak starting in side the brake pedal area from the brake booster . Also had code for steering assist sensor on inside part of column ,that fix is unplug 3 wire sensor ring on column under dash ,that lets it assist all the time . Note this truck has a steering cooler to just below the steering box mount to lower radiator support . So lots of places hoses could leak. Mileage 120k but old 1997 c3500. Also loomed Aires at mass air flow sensor and the bundle by the passenger front of the engine . Note so far it was driven this past week while I gather up hose for repair and no codes or stall happens this past week . I had to wash under carriage after rain stopped Saturday so I could was unit and get to work on before the next weeks work schedule .
