Hit from rear now car won't start

Did you check your fuel lines for breaks or kinks? Any electrical harness under there where hit? Like a fuel pump connector?
You might want to test fuel pressure at the test port on the fuel rail.

well its possible a fuel shutoff could be in the trunk i never new they had cutoff switches on them

Sort of sounds like the timing belt broke-- if you have one

The valves may have hit the pistons & that is why it won't turn over

I don't know any of that is true & won't wish it on anyone,but
it is a place to start

fuel safty switch first to check consult manual for location

I'm sorry but I believe you have this posted in the wrong product category? Please re-post the question in the proper category if this is the case, otherwise you have my apologies. This is the car and truck problem category

Fuel pump won't be the cause. Most likely the relay.

Smart lock? do you have a picture of a red hand on instrument panel? With falcons quite common. Turn & hold key @ start posision, Hit dash upwards on left side of steering colum, If start = faulty smart lock module. I don't know if expodition has smart lock but probably does

check for fuel cutoff switch reset button. these are designed to shut off fuel in case of accident but they will some times be activated on blowout or even when you hit a pothole or speed bump. your local parts house can tell you its exact location, should be in rear window washer compartment or glovebox.

Hello! I don't see a connection between the headlight issue and not starting...However I definitely see a connection with the accident and not starting...When you say "not starting" do you mean the starter doesn't crank the engine or it does crank the engine but won't start? Do you have a meter and a wee bit of experience using one? If you do we can isolate this fault together...Send a comment...Guru...Saailer

Hello. There is automatic fuel shut off switch. When the car is in an accident like you were. The switch trip and turn off the fuel. There should be a red button in the trunk on one of the side panels. If not, call the dealership and ask them were the auto fuel shut off button is located. Also, it might in your vehicle owner manual. GB...stewbison
