Sorry for the delay in responding.
You must also check for spark, and you must check for power to the fuel pump while cranking the engine. Voltage to the fuel pump, injectors, ignition coil, alternator field, and oxygen sensor heaters will only be present for one to two seconds after you turn on the ignition switch. It will go away after that couple of seconds until the engine is rotating, (cranking or running).
If there is no spark during cranking, don't waste your time with the fuel pump. The next step depends on which engine you have.
