when I try to accelerate at normal acceleration the truck hesitates and sputters. It still gets up to speed and drives. If I accelerate very slow it dosen't do it as much. when I drive at a steady speed it is fine untill i try to accelerate. the truck dosen't get drove a lot and i put some gum out and octane booster in and it didn't help. could you give me any and all your suggestions? And how do you check fuel pump pressure and what should the pressure be?

i would start with a complete tune up, plugs, wires, cap and rotor, fuel filter and air filter.
