Hi I have changed my 1.0mpi 8v engine to the 1.4 mpi 8v engine I have no spark At all so I have bought a 1.4 ecu and immobiliser and chip and reader is there any Pacific way on how to change this when battery is disconnected thanks phill

It's a straight swap but you must swap the ECU and immobiliser under the dash. Then swap your key chip and it should be ok
