YOU NEED TO RUN A SWITCHED LIVE DIRECT TO THE FUEL PUMP WHICH BY-PASS'S THE IMMOBILISER THIS SHOULD BE RUN FROM THE IGNITION.VAN WILL ALSO NOT BE CRANKING A LIVE SHOULD BE RUN FROM TERMINAL WHICH GIVES 12V ONLY AT POSITION 3 (CANT REMEMBER THE COLOUR!)TO THE TERMINAL ON THE STARTER(THE SOLENOID DRAW TERMINAL).IF U CAN GET THE CODED KEY FROM THE VAN THE PUMP CAME FROM TRY TOUCHING THE OUTSIDE OF THE IGNITION BARREL WITH IT WHILE TURNING THE IGNITION WITH ITS OWN KEY- IF IT STARTS TAPE THE DONER KEY TO THE OUTSIDE OF IGNITION RE-FIT COWLING! HOPE THIS HELPS
