Hello. I'm AT MY FRIENDS and i Turned off engine and when i came back Upon trying to restart, I got nothing.Car will not start or any dash display. Stering wheel is unlocked but no display lights or messages. Gear shift will not come out of park. I changed the brake switch on pedal, switched relays of possible significance with ones not necessary (Ignition relay, starter motor, Auto trans control Module and Engine Management System Relay.)I checked all smaller fuses possibly related to no avail. It is not the battery. Car locks and unlocks, horn works, dome light. There is a beeping when you push on the gearstick. Brakes are hard. Any imput would be helpful before I spent a truck load to tow to dealer.
