2010 5.4 , no mods. while troubleshooting 4x4 wrench message (4x4 will not engage), last thing I did was check all the fuses in main box (by the radiator). all checked good visually. I think when I removed the PCM relay it activated the anti theft. Truck wont start now, everything works except the engine, it doesn't crank, got anti theft light on now
