05 expedition no lights on dash, no start, no shift

[kendrell]

Hi my truck wouldn't start after I cut it off at gas station. Dash didn't light up and wouldn't shift out of park like it's lock, my headlights and break lights work and interior lights but not the dash board, radio, and when I turn the key there's nothing, I check the grounds, swap relays I'm at a lost

I'd start with testing the ignition switch.
