You "could" try changing out the fuel filter, before investing in a fuel pump. It could be clogged up with junk from the gas tank???
But if your not hearing the buzz of the fuel pump each and everytime you turn the key to the on position, then I suspect the fuel pump. Butch pointed out his replacement of the fuel pump connector. Unless I am mistaken, it is located on top of the fuel tank, which means ya have to drop the tank to get to it to replace the connector. It could be just a dirty connector, or lose, or just disenigrated.
