My gmc pick-up truck won't start. The fuel pump was delivering fuel to the carb. I changed the fuel pump and it ran for a couple of weeks. Then it quit again and wouldn't start . I noticed the tanks were not switching when I used the swtich in the cab. I replaced the valve that switches the tanks. I checked the fuel lines for obstructions I didn't find any clogging. I also replaced the pump push rod. The fuel pump still does not deliver fuel . I am at a stand still. P.S. I donated before I submitted my question. Enrique L. Gutierrez
