You could check all the fuses. One may have decided to go. You could pick up a fuel pressure tester online for about $30 and it'll tell you what kind of pressure it's generating. If it had a mechanical fuel pump (which it doesn't) the lines might just be dried up, and the pump lost it's prime. No, maybe that's a stupid idea...
Can you hear the pump come on when you turn the key? It's a very faint high pitched hissing sort of sound. If not, you could try to check for voltage at the sending unit (pump).
