Make sure you have power to the fuel pump. On this model you should hear a quiet high pitched mosquito in your ear sound when you have all the lights on the dash panel just before you turnover the engine. If push comes to shove, take the fuel pump out, keep the power on it and run it through a bucket to see if you can at least pump water through it. Make sure you let it dry out all the way though before placing back in the tank.
yes you should be able to hear the fuel pump run for about 5 seconds once the key is turned to the on pos. check to make sure you have spark. if you do try having someone spray air intake or carb cleaner into intake manifold while you crank. If the truck starts right up for a second (or stays running as you keep spraying) Id say you have a bad fuel pump and id change the sending unit also. (First check the fuel pump fuse and fuel pump relay) GMC and Chevy are nororiously known for having bad fuel pump/sending unit problems. I have prob changed over 60 myself.
