Hi guys urgently need help over. couple of months ago had a crash and managed to crack the bottom of the engine case was told by mechanics I will need new engine. got a replacement engine but the engine came from the pre-face lift 3, mine being a face lift the wirrings wont fit the replacement engine.

so I just used the bottom block of the replacement and used the top block of my engine. put everything togetther tried to start it but wont start. I've taking the car to few mechanics but can't seem to get it to start. they all say there is no spark at the ignition. now I am getting fustrated with it, so guys any help would do, I need to get it started i've been waiting too long.
