Right, another code reader came today and this one gives you all sorts
of diagnostics and real time displays from all sorts of systems.
Whilst running some tests the ignition light was coming on, the clocks
dying but it was still starting ok.
The only system that didn't seem to want to display any metrics was
the 'Instruments'? BCM, ECU, ABS etc all chatted ok (on the different
pins as previously discussed here).
Tried the same thing in the Corsa C with the same results so I'm not
sure if it was a valid test or not (and cleared a few codes out of the
ECU whilst there). ;-)
Going back out there later the Meriva wouldn't start (span over ok)
with the dash showing these:
Ignition turn on:

A couple of seconds later and from then on:

However, the Immobiliser status read as:
Ignition Status,On 12V
Transponder Key,Transp. Key 1
Transponder Status,Correct TP-Key
Transponder-Key 1 Status,Programmed
Transponder-Key 2 Status,Programmed
Transponder-Key 3 Status,Not Programmed
Transponder-Key 4 Status,Not Programmed
Transponder-Key 5 Status,Not Programmed
Engine Request,Received
Immobiliser Signal,Transmitted
Security Wait Time,Inactive
Programmed Outputs,None
And that looks ok to me so if it wasn't immobilised, could we be back
to the crank sensor or could a dash plug fault have the same effect?
FWIW I found my original USB ELM 327 V1.4 and OBDAutoDoctor demo saw
the interface and car OK but by that time it wouldn't run so I
couldn't see if anything was going on. Maybe it will be ok in the
morning.
If it starts in the morning I'll see if my mate can put his Suntune on
it.
