Any responses. Is it possible that someone could intentionally do something to cause my Explorer not to crank? I have read things on the internet for hours, watched countless YouTube videos and had knowledgeable people have a look. The battery is fine, the starter tries when the connections are bridged,. Turn the key and the dials move, lights come in but no crank...just the red anti theft light flashes rapidly. I ask if someone could do something because I suspect someone I know who has the smarts to do something like this. All I can think is the programming has been tampered with and now the key and the Explorer don't communicate. Plz help

That's a problem. You have to scan the vehicle and see what's going on. Maybe the receiver in the switch is damaged or your ECU has to be retuned to make it recognize the key again.
Same thing driving and car shut off try ti turn on the security light flashes code 16...but can't find the fuse for it and I don't have any burnt ones to tell...
