1994 Mercedes E320 Coupe - wont start after engine swap
 

Ive just swapped an engine into my 1994 E320 Coupe, The car wont start now, the spark plugs are not firing. The car was running before I swapped the engine out - had a warped head / blown head gasket. Any ideas on what could be causing it to not start? I know on Rovers you have to swap the flywheel when swapping engines as it links into the immobilizer, is their something similar on the Mercs? Thanks
