Fuel pump would not have any voltage if engine is not running. It would have voltage briefly when ignition switch is turned on and unless you are cranking the engine, there would be no voltage. If no sparks are available, the fuel pump relay would not be activated as well during cranking.
The injector should have battery voltage and if it shows 9 volts, that could mean the battery is not fully charged or there is a loose connection somewhere.
How about the ignition coils, it requires one of the wire to have battery voltage as well.
