The Faulty Fiesta (Stall, No-Crank, No-Comm)

This 2012 Ford Fiesta was dragged in on a dolly from almost 6 HOURS away as an intermittent STALL, NO-CRANK. The PATS anti-theft light illuminates and communication is lost with the Engine Control Module. After the diagnosis, the owner took it back and tried to fix it...but still had the SAME PROBLEM! Is it a COMEBACK? What to do now?? THINKTOOL PROS: https://www.amazon.com/dp/B08XXWHQVJ?... Enjoy! Ivan
