Default 2bar boost reading and odd fuel gauge behaviour.

I’ve a curious fault with the Ur since its return from restoration and I’ve spent several hours going through wiring diagrams and the car to no avail.

The core symptom is -

With ignition switch live, boost gauge reads 2bar and fuel gauge reads about 6 gallons low.

With the ignition switch dead (key on but immobilised) it is fine.

With ECU disconnected, it’s fine.

Car runs fine in every other respect.

Has anyone experienced similar or knows any pointers?

All thoughts greatfully received.
