lift the rear bench up to reveal the fuel pump and do an igniton cycle or power up the pump and listen if it runs. if it doesnt run check the two outer thick wires of the plug to see if you have battery voltage coming down them (one is + one is - obviously) if you have 12v then the pump is knackered. if you dont have voltage check the fuel pump relay under the drivers side dash. if still no joy then start doing wiring checks to the pump.

if you squirt easy start or similar in an inlet pipe and it fires then its obvious theres lack of fuel. as said above also check the fuel filter but if its been serviced at the correct intervals it shouldnt be blocked.

hope this helps.
