1987 tbi...NOT GETTING FUEL

[texassquarebodies]

I have a 1987 4 door 3/4 ton that I an having a fuel problem with. It starts if you prime it, but dies when it runs out of fuel. I do not hear the fuel pump priming, but do hear like a small clank under the hood after the time it would take to prime, like it is trying to get fuel. I did a post search and could not find a clear anwser. The truck has been sitting about a year. I quit driving it because of this problem. I need to get this truck running before it rots away.
