As per the previous posts suggest, you've probably caused major damage to the ecu.

All you can do now is to first disconnect and then fully charge the battery and then reconnect and check EVERY fuse fitted to the vehicle (exterior and interior fuses) and pray that you've been extremely lucky and the fault is limited to a blown fuse.
