Agree on the fuel system. If you're not getting fuel to the cylinders, it won't start. Fuel pump, relay, or filter could be the problem, there is also a screen inside the tank that could be clogged, also.

The usual consensus is that the filter should be changed with the pump, just for paranoias' sake.

If you wiggle the relay to insure that it's seating the contacts properly, you may just "get lucky" and fix it. But don't bet on it, you're eliminating the easy stuff.
