Burnt key impressions into my fingers

The car set for an hour and 30 minutes before it Croc back up and then I drove it the check engine light went to flashing and then I pulled over and cut it off and it did not crank for the next 5 hours I'm saying I tried to go under the hood and remove a relay and end up putting a screwdriver to pry it up because it like it was stuck so I needed a flathead to pry it up it made smoke I redid the line that was burnt from the fuse box under the hood now it's not letting power get to the inside of the car
