My absolute heap of a Mondeo has finally had it's engine rebuilt having suffered head gasket failure.
It's all back together, and we go to start it but convers is coming up immobiliser active.
Battery was flat, now charged.
All connections are good
No faults showing on diagnostic, nor will it give the option to reset immob.
Fuse OK (Left row 4th down)
Tried removing battery (Which is 6 months old)
