Maybe the fuel pump isn't working. Check the fuse for the fuel pump, relay, and the fuel pump itself.
The car has fuel, in fact, I put two more extra gallons in there. I borrowed a OBD-II to scanned the DTC (Diagnostic Trouble Codes) and got nothing. Also, checked the fuel pump fuse (located in the trunk) and other fuses in the hood (passenger and driver side) and everything looks fine.
Today I am going to check what BENZ0786 has suggested.

With the key on the number 2 position, can you hear the pump? It should run long enough to pressurize the system. About 5 seconds in my car.

I actually had someone touch the fuel pump while I put the key in number 2 position, the fuel pump didn't move nor vibrate...
Bad fuse, or bad relay, or bad pump, or bad wiring (doubtful). The pump is supposed to turn on with the key in the #2. You can DEFINITELY feel it.

Remove the air box to get to the fuel rails. The passenger side fuel rail, toward the front of the car, will have a black plastic screw on cap. Remove the cap and you will find a schrader valve, very similar to the air vavle on your tires.
If your pump is pressurizing the rails, then gasoline will squirt out when you depress the pin in the center of the valve. Have a towel handy. You can also put a gauge on this valve to determine if your pump is providing the necessary pressure. Search the forum for the pressure rating.
If gas does not squirt out, then pump is not pressurizing the system. If you are going to replace the pump, then check the pump and filter bracket. If it is rusted up (Massachusetts winter salt), then buy the bracket ($30 or so), because it will likely fall apart when you take it off--cheap MB tin.
You can also replace the filter. I did NOT find it to be an easy job.
