Thanks for the reply.
I note what you say about the code being related to the fuel pump relay but that's not what the code reader is saying - it's saying it's a DVE spring test fail, which to me seems to fit with the click I get from the throttle body when the ignition is switched on. I have read that I should hear the motor running in the form of a hum while the TB is recognised and the settings updated, Despite that, I have changed the relay for a known good one so it isn't that component.
When you say the ECM, is that your term for what I would call the DME or ECU?
Can you advise regarding the spline nuts?
