Cannot seem to get the fuel pump to work a

Hi i have an mr2 that has been in storage for about five years, that was working ok when left but now i have tried to start it and cannot seem to hear the fuel pump kick in and no petrol to engine. i have tried to send power to the pump via the connections next to the fuel sender however still cannot hear the pump start up. the car was left with half a tank of fuel five years ago, so do you think that the fuel has damaged the pump over this time? i have put more fuel into the tank and have undone the fuel plug at the bottom of the tank to find that the fuel will discharge so i dont think the fuel has gone off. the car is the mark 2 model with the tank in the middle of the two seats, it is a 2000 cc 16 valve GTI. also if i put fuel into the air intake the car will then start until the fuel has gone.
over to you guys
