Open the tailgate.  Just behind the rear seats is a raised section.  The
fuel tank is just below this.  If you lift up the carpet, you will find the
inspection hatch for the pump and gauge.  I would check the electrics before
assuming a faulty pump.  The fuel pump relays often go faulty.  Try bridging
the contacts (details in Haynes) to see if the pump comes on.  There is also
a safety feature built in which doesn't turn the pump on unless there are
regular pulses coming from the distributor to the lv side of the coil.  

I have the opposite problem to you.  My pump is VERY noisy.  People on the
street turn round to see where the noise is coming from when I drive past!
