A driver ran a red and t-boned us. Curtain airbag saved my head and my girls head in the middle seat.

The cops drove it to a parking lot and I was going to try and drive it home but it wouldn’t start. I think the fuel shut off switch got tripped from the impact. Any ideas how to reset it? Not much online. Some have a button but others have a fuse/relay you might need to pop out and back in. Any ideas? I want to try to get it home without towing if possible
