Will not start

I drove my car and shut it off, when I went to get back into the car and turn it on, the engine would turn over but the car would not start. (All the lights/radio worked) We did attempt to jump the car and upon trying to start it, it did the same thing, the engine turned over but it did not fully start the car. We towed the car to a friends garage and he said he thought it was the fuel pump. He replaced the fuel pump and now when he tried to start it there is no sound what so ever when the key is turned. No lights/radio either. The vehicle is ten years old with 180,000 miles on it and has never given me any problems. I am not sure if it is just time to get a new one or not. Any idea what the problem could be?
