Need to know make and model to help. If it is a Chevy, when you turn the key on you should hear a 1 or 2 second buzz. That's your fuel pump pressurizing the lines. If you don't hear it, the pump (in tank) could be toast. I fixed mine once by turning on the ignition and hitting the bottom of the gas tank with a rubber mallet a couple of times. After the second hit I heard it buzz. Could have had trash in it somewhere.
Let us know the info on the truck and we'll try further to help.
