The pump will run all the time the engine is running as it should prime the system when you 1st turn on the ignition and then stop after a few seconds, it'll then run again once the engine is running.
I did think this this year was still on carburation hence my carb comment but as your's is injection the pressure will be higher (30-37psi).
So I'd 1st locate the pump ( should be under the car close to the tank) and see if it runs, if its doesn't 1st investigate its relay in the fusebox and see if theres 12V at the fuse.
If these are both OK (relay clicks on with ignition) then check the pump terminals for corrosion and you run a new wire direct from the battery to see if the pump will actually run - so confirming if the fault is with the pump or the relay
If the pump is running with the engine then its likley that that the ECU isn't opening the fuel injectors, if the injectors are working you can hear them click - its difficult to hear them with background noise so use a long screwdriver like a stethoscope, placing the handle end in your ear and the metal tip against the body of the injector whilst your assistant turns the engine over.
Also check the ECU power and crank speed sensor relays and fuse and mentioned for the fuel pump
