Look up bst. It's a fuse that is on your positive terminal red wire. Pretty much you need to replace that wire and it retails for about 430. I believe someone on the forum can order one for under 200. It's a safety feature so that your car doesn't explode and cuts off the engine from turning on after the accident depending on how bad it is. See if the red wire is loose by the black box running towards to the front of the car. Same thing happen to my car when it got rear ended.
