   I have been unable to start my 2001 VTR for two weeks now as i connected starter motor up the wrong way . Since then the car cuts out as soon as started and the immobiliser light is on the dash. I have asked a mechanic and he reckons that I will have blown the ECU and Immobiliser block. They require replacing along with a new key. Is this a big job to do or is thee any other (easier/cheaper) methods to get it running again. Any help at all woud be much appreciated.

   I have not had it fault code read yet as no insurance on the car at the minute. The car turns over and seems to fire up but cuts out immediately and the immobiliser light is flashing on the dash during all this. I really need car running again but have not got the funds to try a process of elimination.
