Got into accident car wont start where is kill switch

This vehicle is not equipped with a kill switch. You will have another problem causing your no start

Could be a million things still. Your fuel pump is dead, theres a clog in the lines, fuel filter is done for. On some fords, there is a kill switch located somewhere for the fuel pump. If you're not smelling gas (flooded cylinder), I'd look at the fuel pump fuse or that kill switch, if those are fine maybe replace the fuel pump.

it looks that maybe you have a faulty new thermostat or is not the correct model. also check for the fans and fan relay.

There is a "Kill switch" that shuts off the fuel pump whenever a crash is detected. It should be located where this is at in the owner's manual ... When you say "Kind of Loose" are we talking "I can rattle the key a bit" or "I can pull the key out with the ignition in the 'run' position" ?

The fans must come on before everything starts boiling. Is there another temp sensor besides the one you replaced? Did you replace it with a switch type rather than a thermal resistor type. The temp sensor should tell the computer to turn on the fans and the computer is supposed to turn on the fan relay and it turns on the fans. If they work with the A/C, that eliminates the computer output, the relay and the fans, and gets back to the temperature sensor.

Check your inertia switch. This is usually located in the rear interior of the vehicle. It has a reset switch you hold for 3 seconds. It is a safety switch to kill the fuelpump in an accident. Can trip with door closings.

check nutral safety switch,you have power on the starter, now is ignition to starter power

CHECK YOU BST CABLE. BST CABLE IS YOUR POS. BATTERY CABLE. IT HAS A FUSE IN IT THAT GOES OF TO KILL THE CAR ELICTIRICAL SYSTEM WHEN YOU GET IN AN ACCIDENT SO IT WONT CATCH ON FIRE.
