Default 2003 Silverado 2500 HD Fuel pump issue

My fuel pump is acting up. I replaced the fuel filter and that helped out quite a bit. I checked the grounds and all that stuff. I have done everything I can think of short of exposing the fuel pump. When I turn my key I can tell if my truck will start by the fuel pump running or not. when the pump doesn't kick on I just get under the truck and bang on the tank and try again and the pump kicks on. Is this a wiring problem or is it the pump just going bad??
