R53 swap!!! Need help!!!
 

Hello everyone.
I finally managed to put a new 2006 r53 engine into my old 2004 non S mini cooper. I've done with the all wiring work but I'm having no crank problem right now. I am using my old ecu at the moment and thinking that is my problem. When i try to start it, i hear the fuel pump work also the throttle body opens but starter wont work. Its like when you try to start your mini with out pushing the clutch pedal.
What else could it be?
