Could possibly be the fuel pump. Do the test mentioned by geez. If you still don't get any fuel out of it (at least 1 pint in less than 30 seconds) work yourself backwards.

Remove the hose from tank to the fuel pump and replace with a 2-3 foot section of fuel hose on the inlet side. Place the other end in a one gallon container of gas placed under the truck. If engine starts and runs okay than the line from the tank is either clogged or the fuel filter inside the tank is clogged.
