I found this online, I dont know if it is your fuel pump but if it is.......fuel pump relay and a module in this vehicle to be concerned with... the relay powers the module, and the module passing current and ground to the pump. The fuel pump relay is mounted in the passenger side foot well area, behind the carpet of the center console just below the radio area.... it is attached to the MFI relay as a paired unit. The relay module is located on exactly the opposite location, in the driver side of the console, again below the radio area mounted behind the carpet. My concern at this point would not be so much about the fuel pump not coming on, but that you are not getting injector pulse either. The fuel pump will only power up if RPM signal is detected in the PCM. Similarly, if there is no RPM signal, your injectors will not fire either. If the fuel pump relay is bad, you will still get injector fire (just nothing will come out); same goes for the module. I would be focusing on your MFI relay (attached to side of fuel pump relay), the associated fuses, and making sure your crank sensor is working. If the crank sensor goes out, you will have no spark, no fuel, and no injector pulse. Similarly if key power lines are down to the PCM (via fuse or MFI relay failure), there will be no reference voltages, and therefor no spark, no injector fire
