Is it possible that your gearstick movements merely coincided with the intermittency of the fault? I've had starter motor faults that resulted in similar, seemingly random behaviour.

I don't think so, I had the key twisted into start position and held it there with no "click" of the relay.
As soon as I moved the stick it started.

If the F125 checks out, have you checked the main battery cable on the drivers side chassis? When that corrodes out you have power to everything but no starter action. If it’s getting crusty (damp and salt won’t be helping at the moment) it might start causing intermittent no start?

Also check if yours has had the recall done for a slipping park interlock cable - if there's no fault codes suggesting F125 it'd be worth checking....

Thanks for the input folks, I'll not rule any of them out.
But right now MJs F125 theory fits the symptoms way better.

And I investigated that recall Adrian, ages ago, and I'm quite sure it's not relevant to my car. Nor does it match the symptoms.

Right now I really would like to know more about bypassing the F125 starter solenoid lock...…..

I don't appear to have a photo of it unfortunately. Its J207 which Elsawin claims is top left in the relay panel in the footwell. I remember it being more in the middle of that panel tbh. The manual has a jumper between pins 2 and 8 per this diagram:



I used some 2.5mm wire and some 6.3mm terminals to bridge 2 & 8. The factory one is a bent bit of copper, but I have no idea what the number is so just made my own.

If you jump power to pin 8 it will spin the starter which might be diagnostically useful.

Late at night and just been sampling 27 and 36 year old whiskies, but that looks good.
I'll investigate further tomorrow.

Do you remove the relay and put the jumper in or need both?

Also I can't recall the layout there, is that the main panel under the "board" under the passengers feet, or the section that I think is above it?

+1 for the earth strap. I changed a starter motor on my drive before I found that corrosion on the cable to chassis was the problem!
