A car usually won't run if the fuel pump is bad; fuel injected cars (all modern cars) need a certain amount of fuel pressure to run, and the electric pumps normally fail all at once. Rarely will a pump partially fail, providing only low pressure. When this happens the car will idle but the further you open the throttle the worse it'll run. If this symptom is happening to you, though, it's much more likely to be something else (weak spark, bad fuel pressure regulator...)
