One quick and easy way is to wait until after the truck has been sitting cold for a couple of hours, then turning the key to the "Run" position and listen for a buzzing noise from behind you or have a friend open the gas cap and listen for the sound of the pump spinning inside the tank. If you don't hear anything, you'll need to use a multimeter at the tank fittings to check for pump voltage. If you do hear the pump working and it still runs bad under load, you may want to replace the fuel filter.
