About fuse problems on 2002 windstar

What is your question?

i asked the other day..when i turned my car off at the gas station..when i turned it back on ..i couldn't get it out of park..had no brake lights or turn signals..chcked the bulbs they were fine..now i have no dash lights, the radio stopped working, the windows wont go down. My son and son in law changed out all the fuses today inside and out and they still don't work. They also took it to auto zone and had a test run on it and all the came up was a fuel gauge sensor..which to me makes absolutely no sense but what do i know..this is way beyond anything i can afford i think and no one seems to know..thanks
