Pump is in the fuel tank. Filter is under the truck in the fuel line. You can't miss it. To find out about the pump you will have to do a pressure test.

Well, I don't know where you are located, but some parts stores offer free loaner tools. Not totally familar with your truck, but suspect on the fuel rail should be a schrader valve to plug a gauge in to check the fuel pressure. I am thinking the pressure should be around 50-60 psig.
