Car wont start. Nothing electrical (lights etc) work. Battery/alternator are good.

The story,
-My car hasn't left me stranded before. I stopped for gas and turned off the engine and when I went back to start it, nothing happen. No crank, no power to anything at all.
-AAA came and tested the battery and it was good, he checked the cable and connections and everything was fine. He tried jumping it and putting in a new battery but no luck.
-I checked all fuses and relays but still no luck.

Please help!!! I would appreciate it :D

Check your main relay to see if you have power there, again.
Check your ignition switch.

Check your fusible link near the battery, about 12-18 inches from the power cable end. Also check your engine ground cable, if loose, your car will not start.
