If you mean fuel pump, the engine would not start. On some cars you can hear the pump energize when you turn the key to "on" for a few seconds, then a "click" which is the relay and then pump would turn off untill you start the engine.

The only real way to be sure is to have the fuel pressure tested with a mechanical gauge. If no pressure, then pump, fuse, relay or wiring.
