Sounds to be a loose connection of the main power or ground. Loose connections will allow you to have power to lights and things but as soon as you put more of a load to it you loose everything. So question then, do you loose hedlights if you try and start the car? If so its more than likely a connection issue, if not then you have something else happening. But always check the obvious first, fuses, connections.
What this guy said... even with no fuel pump in the car you can still turn the key and it will try to turn over, that is of course, everything else working. If you have dead silence, and you are getting power to everything else.... it could be a couple of things.
A bad alternator could also be the problem. This happened to my wife when she drove my 240sx in the morning to work. It would be very early AM and when she got in, started the car, flipped on the lights and turned on the blower motor on high... the car would die within minutes of driving. Everything dead except for the radio and lights - basically what the battery had enough for. The brand new battery the car had allowed it to run for a bit.
I would run the car fine because it was during the warmer part of the day, plus there was sunlight. Less accessories being used. The car sat all day and when I came home it would have enough juice to fire up and off I went. Then I would look at her like she had 7 heads. Also, she was quite frustrated! lol
That at first led me down the path that the starter was on its way out. She said she would stop to drop the kids off, then come out and the car would stall when she tried to back up. Then it would want to start, however the lights would flip up and down with light and the radio worked.....
So yes, despite your best efforts - it could very well be your alternator. Give the car a good boost - provided your battery it good it should fire up. Then take a reading of your volts when running and that will tell you if your alternator is toast or not.
Sorry for the novel, but I'll try to find my frustrated post when I had this problem....
