Is there a Possibilty that there are different engine Variations that might cause non start. ??

i,e It used to be a common problem with cavaliers, Toyota Yaris, Rovers etc for someone to do an engine swap only to find out that they wouldn't start and Eventually to find out that the Flywheel is Different or Crank or Cam Reluctor ring was different etc.

Might be way off the mark but thought it worth a mention, although you would think that it would cause it to set a Fault code for cam /crank Synchronisation.

P.S Have you still got that old Wardrobe. ??
