Try removing the inlet line to the pump off from the tank. With the engine turning over and your thumb over the end of the hose you should feel the suction of the pump trying to work. If not look at the pump or the eccentric area for the problem. Low budget test but it works. Don't particulary like pouring fuel into a carb, took a while for the hair to grow back last time I tried that in the early 70's. heh..heh...
