Immobilizer, ECU issue

Hello everyone, I have a 2004 range Rover l322 gas automatic. I replaced the started (blew fuse link) . Never started after that. My steering column does not lock, so I purchased a emulator. I can get the truck to crank by jumping power to the park neutral wire( while turning the key). But it will not start. I think the ECU is not receiving the code from the immobilizer. I know it's suppose to be a rolling code (I checked the wire from the immobilizer to ECU, no voltage at all) . Im stumped, please help. Thank you

Not to sure about the 322 as I've got a p38 and the problems I've had was it needed re-sync but I'm sure one of the l322 wizards will be along to help you soon

Thank you, do you know a cheap scanner I can resync with?

If you are looking at keeping the motor for a fair while look at allcoms by RSW it is a proper diag tool and would save its cost again and again in the long run.
