Just been reading  back through this again. Sorry if i missed it but did you check fuel delivery / pressure .faulty fuel pump or blocked fuel filter ?

Thanks no i haven't yet, i got myself sidetracked with MAF and crank sensor.  looking at the data during my stall from idle the short term fuel trims did shoot up as the engine died.  1.5 seconds  before the first recorded zero rpm, STFT bank 1 shot up closely followed by STFT2.  However the ignition advance started rising a full 3 seconds before hence I suspected the crank sensor.  I'll put the old sensor back in tomorrow anyway- it was working most of the time  and since it was changed barely runs.

is there a standard way to check the fuel delivery/ pressure?  just carefully undo the supply pipe and look for pressure?  how long after shutdown should there still be pressure? i looked in the guides but can't find it.

I beleive you can check it from the fuel rail somehow but i havnt tried this myself.maybee check that you have a good flow back to the tank / return would be a basic  check to see if pump is pumping and filter is not restricting flow but no doubt someone will be along to advise more presisely.following this sith interest also with regard to the crank sensor issues / etc. .

There is a shrader type valve in the fuel rail

thanks I assume that is under the plenum cover, will test it.  meanwhile the engine will not start at all.  there is no 'bounce' on the rev counter when i try so i am still unsure about the crank sensor despite having tried 3 different ones and putting the old Delphi one, which was working mostly, back in.  I think i will visit a vaux dealer just to put that issue to rest.

I can't remember if the plenum needs to come off, or if its accessible at back. 

[Doctor Gollum]

It's as accessible as the plugs... Piece of piss. Just don't drop the cap or I will laugh. Alot.

And don't have your noggin over it when you press the valve in or you may get an eyeful of petrol

No sense, no feeling...

checked the schraeder fuel valve, it was full of fuel and the pin appeared a bit bent but no pressure.  Cranked engine no pressure or fuel coming out.

 tried to fit a new fuel pump see my new post

hopefully to close this one down, the second hand purple injector relay arrived today and i plugged it in the engine compartment fuse box.  car runs fine, took it for its MOT and it passed with no advisories .

i'm pretty sure the windings on the old relay started to go open circuit in hot conditions and eventually failed completely, causing all the symptoms here, including indirectly these error codes:
0100 MAF (caused by unplugging),
1613 Immobiliser No Or Wrong Signal Immobiliser (low battery),
0560 System Voltage Low Input (low battery),
0230 fuel pump (probably me unplugging the fuel pump relay at some point).

a temporary get-me-home-fix for the relay is to remove the purple cover from it and put a small spring clamp over the solenoid contacts, remembering to remove the clamp when the ignition is off.

I also checked the fuel pressure at the schraeder valve with an £8 kit, it is 3.6bar.

thanks for all the help here, well meaning or otherwise, but most of all the archives. I hope this thread helps someone else sometime.

forgot one other code, in fact the first one that showed and made me change the plugs
p0305 code misfire cyl 5

0100 MAF (caused by unplugging),

0560 System Voltage Low Input (low battery),
0230 fuel pump (probably me unplugging the fuel pump relay at some point).

Agree with all you conclusions, apart from 1613 - was it an old lingering code (I don't believe that one self clears with time), or old that came back after a clear?

Never seen that one due to flat battery.

1613 appeared at the same time as 0560 , both at the time i had pretty well drained the battery trying to start it. not appeared before or since and was cleared by my obd2 scanner.  no codes before  this issue, either on pedal trick or scanner.  so I am pretty sure it was down to a low battery .
