Can you here the fuel pump run for a second or two when you first turn the ignition on? (Note: If you turn the key on repeatedly in short succession, you may not hear it run every time you turn it on, but you should hear it run the first time you turn it on after sitting for a while.)

Is there spark to the spark plugs?

If you answered "yes" to both of the above, the problem is VERY LIKELY the Radio Suppression Relay which should be found mounted to the front side of the coolant overflow bottle. If there are two identical relays there, the second one feeds the aux fan. If that's what you've got, try swithing the wires between the two relays and see if the car will start.
