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!
