Electric not working at all
So i hit pothole yesterday and car just shut down all lights went blank. I checked fuses and relays all fine and wire hareness not touched at all. I put new battery nothing not even door courtesy lights. I check grounds saw nothing loose im at complete loss

check your ignition switch and main relay.
I believe they are under the steering wheel cover.
(im not sure this happened on my DD not to long ago and that's what fixed it for me)
do you have a lot of keys on your keychain?
does the ignition cylinder feel tight or loose? (do you feel resistance when turning the key?)

I would highly recommend a new ignition switch. it is probably the one from the factory so the contacts are probably worn out and that pot hole might have misaligned them.
you should feel some resistance when turning the key over.
its a relatively cheap part I believe.

well its clear that your car is not recognizing the on position for the key.
that leads me to believe that it is the ignition switch since that controls if the car is on or not.
if there is no contact between the contacts, (which it sounds like) your car will not get the power signal and your car wont have power.
what side of the car did you hit the pothole on?

Fuses
It all points to one of the main fuses under the hood. I would pull each one out, clean the contacts, and reinstall. I would go as far as checking each one with a multi meter to make sure that the bump didn't dislodge something in the fuse itself.

I did that ozzy i thought same thing. i also checked alternater fuse and replaced am1 fusible like cause little corrosin on it .When i tried new battery i got little spark sound so i know there is juice coming from some where just weak.

Ground
If all the fuses are good, and you are SURE the battery you bought was fully charged before you bought it, then all that's left is the grounds. You may have to disconnect, clean, then reseat all of them.

I have a 400 so not really qualified to offer ideas but don't the 300 s suffer from the wiring harness rubbing on the left wheel when lowered? Think the harness took a bad hit when you hit the bump?

First thing i checked was harness. I thinks checking each ground is last option i even checked ecu
i didnt have one blown capacitor actually looked fairly new thanks for responses.Im pulling my hair out trying to figure it out

Ecu
A bad ECU wouldn't explain why not even the lights come on when you open the door. If a wiring harness is frayed, I doubt that one wire being cut on the bump would cause the loss of ALL the power, just certain systems.

Is your SC bagged/lowered? If it is you might have clipped the main harness underneath the fender well. This has happened before so it has to be something liable to get hurt from a stiff jerk.
