Assuming this is an old body style truck(GMT400), they are very noted for weak fuel pumps. The newer trucks aren"t a whole lot better. On the '99 it will be much more expensive than the '96 and early '97. Buy a new relay either way. Listen for the pump while a helper turns on the key. Should only come on for about 3-4 seconds. If it doesn't come on, put the new relay in and try again. Do a pressure test. MINIMUM is 58 psi. Any less and the pump needs to be repalced. Replace only with a Delphi or ACDelco brand pump. The schrader valve is just right (looking at engine) of the centre of the engine, below the Vortec box. On these trucks the electrical connector should be part of the pump assembly, unlike '96 and '97, but if not check for an updated connector, and check for an update to the truck side connector either way. Replace the fuel filter when replacing the pump, it's required for warranty. Replace the in-tank sock if it's not inlcuded with the pump assembly.

The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
