2001 Chevy Malibu fuel line

I ran my car out of gas on the side of the road, went and got my gas and put it in the car. The car still wouldn't start. I can still hear the fuel pump when I turn the key. We have tried putting more gas into it, we have tried turning the key 8-10 times while battery is being charged. I know it is not the theft system, I am familiar with that already. We have checked all the fuses. We have also check for the blue spark, and it does have it. So we know it is a fuel problem. When we press on the valve on the fuel rail to check pressure there is no gas coming out and no pressure. Could the filter be plugged or what else could it be?
