put it in a vise, fill it with diesel or atf, hook up a battery to the main body and the electric fuel shut off to turn it on, hook up your injector lines and injectors, put a quart jar with diesel and put your in and out of the injection pump in the jar, then turn the pump with a drill and push on the throttle and see if you get the injectors to spray, you might have to bleed the injector lines
