You need to check fuel pressure at the fuel rail with a mechanical gauge. Even though you can hear the pump, it is the fuel pressure that runs the car.

Check fuses and spark, if PCM does not see an ignition reference pulse it will turn pump off.

If it has good fuel pressure at rail and spark, then check injectors with noid light, see if they are firing.
