There is a switch somewhere that shuts the fuel pump off unfortunately I don’t recall where it is, I think it might be in the trunk somewhere check your owners manual.

If an air bag went off, you can't start the car. Air bag needs to be replaced and then hooked to the dealer type scanner to reset everything. Nothing you can do except jumper out the relay in the fuse box as an emergency "gotta drive it" thing.

Theres no fuel cut off switch on a dodge.
Ive got a charger right now that blew the steering wheel, knee, side, passenger and seat belts. Front was severely damaged. Came in yesterday, fixed the damaged wiring on the abs pump to fire it up. Has codes in every module too. Radiator and condenser is fine but fuse box took some damage.
Ok now for your no start issue. What kind of damage did it receive? Front? Side? Rear?
Did abs pump get damaged? Its a key component in the start system. Most of the modules talk to it for the stability and traction control. Does the ignition come on? Need a little more info to help you out. Check ALL the fuses. Make sure front and rear fuse boxes are intact. Then make sure the relays are still in it. Seen them fly out.

I think you may be right, now that I think about it it was my mustang GT that had a fuel shut off in the trunk somewhere. I guess my memory is starting to fade lolhahaha

Ya ford loves the inertia switch. Cant think of a vehicle they make that dont have it. Dodge, gm never has run it. Gm relies on the oil pressure as a safety shut off.

That's not been my experience at least with one car. Both driver and passenger air bags deployed. Seat belt pretensioners deployed.

Had car towed to shop. It sat. After some few days got word car was declared a total loss. To move the car to a more out of the way location a shop employee went out and got in car and started the engine right up. Asked and he said he didn't have to do anything to get the engine to run just turned on the ignition key like normal.

The airbag inertia sensor triggers the ASD relay and kills ignition and fuel pump. It does not always trigger the air bag to deploy. The hard core Jeep guys hate the modern Jeep because a hard klunk into a rock can shut the vehicle down. The Jeep guys have a dozen work-arounds to kill various sensors to keep moving and not be disabled on a trail in the middle of east bumblast. Another thing that happens in modern Jeeps is the snapping off of the fuel pump pickup in the tank after an impact. Voltage to the fuel pump and the pump runs but no fuel comes out because the pipe is broken inside. An aftermarket pump solves that problem. Why a particular vehicle won't start after a impact needs to be investigated. My Grand Cherokee is weird to the point that if the engine is running with the hood open, a switch kills the engine if I put the transmission in drive. I have the hood switch jumpered out. My 2013 RT Challenger was disabled when I accidentally disconnected an air bag. After I found the wire I cut, a PCM reset got it running again. Hence, my above post.
