Your vehicle is equipped with the Ford PATS - Passive Anti-Theft System. Depending on the year, make and model will affect what all it covers. The basics you are looking at are the ignition key, dash cluster and PCM communicate electronically. If the vehicle is attempted to be started mechanically without the electronic completion of circuits then multiple items can happen from shutting down of the starter, fuel pump shut off and injector stoppage.
When the key is removed and the system is active the Theft light comes on as a warning.
It is not unusual at all for the home mechanic to try and work on these vehicles and cause electronic component damage which can immobile the vehicle and require some rather costly repairs.
