My car was siphoned and I drove it until it was.

My car was siphoned and I drove it until it was completely empty before I realized bet had been siphoned. I put a gallon of gas in it and was on my way to fill it at a station only 3 blocks away when it stalled again. I called my roadside service who put an additional 2 gallons the tank, but it still didn't start. The tow truck driver told me he could not hear the fuel pump when I tried to turn it over. I had it towed to my friend's house to see if I could work on myself.
So far I have replaced the relay and the fuel filter, but still nothing. I need to know what to do next. I can not afford to take the car to a shop.
