How about the details in the Electrical Guide - free download here or JagRepair.com - Jaguar Repair Information Resource

 

Usually that wire doesn't go from ignition to starter. It goes from ignition to immobilizer, then another wire connects from immobilizer to starter motor. So you could have an immobilizer fault.

I recently fixed a Ford Focus with a similar problem. It had blown a fuse on the immobilizer supply. It wouldn't hurt to check your fuses. If that doesn't fix the problem, follow the link suggested to electrical info and start a slow and steady diagnosis procedure.

Don't give up. Anything is possible with enough determination and patience.
