Fuel Pump Problem?

My 02 reneault scenic dci stalled and wouldnt start again. The starter motor, fuel level, battery and terminals have all been tested.

There doesnt seem to be any sound of the fuel pump when the ignition is turned on. we've also checked the immoboliser.

Is it something simple, or do i have to get the fuel pump out, and if so, how do i go about it?

Oh, and the relays have been checked, but unsure which of the relays is the fuel pump relay. Anyone know?
