There is a bank of relays on the driver's side fender. You only have an ASD relay. It should be the 2nd from the front. First one is A/C Clutch, ASD, Radiator Fan (2.5L) and Starter Relay. More than likely, your fuel pump has failed. Sometime you can get it working by tapping the fuel tank with a rubber mallet while someone turns the key to start the engine. What usually happens is that the motors brushes either wear out or stick in there respective holders thus not making contact with the armature. If you are mechanically inclined, you can unplug the relay connector and check for 12 volts at the relays connector terminal #30 to ground. If voltage is present, you can run a short jumper wire to terminal #87 on the relay connector. this will power up the fuel pump circuit. CAUTION: If you jump the wrong terminals you WILL HAVE to replace your Powertrain Control Module.
