1999 Jaguar XJ8

Engine Performance problem
1999 Jaguar XJ8 V8 Two Wheel Drive Automatic 79800 miles

car is a no start, no spark and no injector pulse. Originally car had these issues plus no compression, but that has been restored. Message center displays the following: failsafe engine mode, traction control problem, stability control problem, gearbox problem, incorrect part installed. Someone unhooked the trans cable because they did not know how to get car out of gear. The crankshaft sensor was replaced as well as the battery. Any help would be appreciated.

Maybe a wiring fault or a bad computer?
