inertia switch maybe in the passenger kick trim panel, may be tripped and killing the pump.

starts runs and dies is usually the immobiliser kicking out.

if the light by the clock is now going out when cranking hopefully the immob is switching off as it should.

try giving the fuel pump a fused temporary live supply to eliminate a broken wire from the inertia switch to the pump.

if the inertia switch is ok and in the reset position (i.e not tripped) and you can make it run from the temporary wire then i would be looking at fuel pump fuses and associated wiring.
