Lie down on the ground by the fuel pump / filter and have someone switch the ignition to just before start.
If you do not hear the pump run, then turn ignition off and go to the front of the fuel rail on the engine right side, remove the black plastic cap and press in on the Schreader valve ( covered with a rag so you don't get sprayed if there is pressure ).
When fuel stops flowing, do the listen test again.
If still nothing, then one of two things :
1. the RCM is not supplying 12v to the pump.
2. the pump has 12v, but won't run ( a voltmeter might come in handy for this )
