Hello.
Can anyone advice if it's possible to do the 'paperclip' test on this model of Omega (2002).
I have a Sealy code reader, but it doesn't seem to be able to talk to the car for some reason so I'm stuck for trying to find out why the car won't start.
I'm suspecting it's an immobiliser issue as the car with the spanner dash light sometimes flashes on the dash, but not always.
The car turns over healthy enough (when there's plenty of juice in the battery), but doesn't seem to want to fire.
I've check the key fob and there is what looks to be a very small black box in the corner of the key horseshoe part but it isn't loose so I don't think it's the transponder that’s come detached from the key causing an issue.
If it is the immobiliser side, does that mean that I've got to get another immobiliser ECU or can I get it repaired of sorts?.
Any advice or pointing me in a better position would be helpful please - Thanks.

paperclip test doesn't work on the 3.2,try the pedal trick instead http://www.omegaowners.com/forum/YaBB.pl?num=1189022687
crank sensor would be top of my list :y

Had the same problem-turned out to be the crank sensor.

Thanks for the advice, will give it a go tomorow to see what I come up with?.
I did wonder about the crank sensor, so will see if the pedal trick shows that as I would be interested to see what is causing the fail to start as it's just suddenly happened :-?.
Cheers :y

sometimes the crank sensor can fail and not throw up a code
-
Well I've just done the pedal trick and the code has come up with code 0335. Thanks to the helpful v6 codes list on here it points to a Crankshaft Poistion Sensor "A" circuit manlfunction , so for those having a guess at it being the Cranshaft sensor, you were right ::) .
You're probably knowing where I going with this now, can someone advise on the part number and if I could perhaps get the sensor discount via Autobahn card or if its a top price from the stealers :-? .
Next port of call is guide on how to change it, which by from other peoples experience it isn't easy !! ::)
Thanks to those who've helped :y

Here you go! ;) ;) ;)
The sensor is just one bolt up by the oil filter, the hard bit is pluging it in uo on top on the engine. :y

Wow... that was a quick response.

We try to please. ;) ;) A crank sensor is a very useful spare to have in the boot. By learning from The Boy when his crank sensor packed up in French France I bought one for my boot. It came in very handy last year when mine packed up one Friday afternoon after the shops had shut! :y :y :y

Sounds like good advice - must put on the 'to do' list. France is not good for Omega spares, or caravan tyres come to that, last time I had a problem abroad had to wait 3 days to get rear disc pads shipped in after the braking material parted company from the backing. After a tyre blowout on the van had to have two tyres flown in from the UK courtesy of the Caravan Club :o :o

I've just crossed my fingers regarding recovery the last couple of times we've gone to France. As our 'van is 7.05 metres long, many recovery firms won't give cover as they have a 7.0m max limit, & I felt Red Pennant was taking the p when they want £200+ for the fortnight's cover.

No longer an issue for me as SWMBO sold my damn caravan! It was the right time to sell but I was sad to see her go. Roll on retirement because I am buying another! :y

Hi,
Before you get too excited, and changing sensors etc.
Disconnect the fuel hoses going to the engine, pack well around them with rag etc, then try starting engine and see if fuel comes out all over the place !!
Turning ignition on does not start pump, engine has to be turning over.
If it does, carry on investigating sensor etc. If not then you have a faulty fuel pump.
Mine did exactly like yours in car park in town. Just wouldn't start although had been running perfectly. Everyone said duff sensor, so I changed sensor, a right sod in a busy pay car park, especially getting to where it is plugged in at the top of engine. Still no luck, eventually after methodically checking systems, found fuel pump duff.
There are other ways to check pump, but you need to know which relays etc. This is simplest I know for quickness.

I would of imagined if it was the fuel pump, then there would of not been any fault codes showing up for the crank sensor when I did the pedal trick. Had no faults come up then would be a good to look elsewhere. But code came up showing crank sensor. Wouldn't hurt to have a spare crank sensor anyhow as it sounds to be a weak point on the v6's.
Will check for fuel later in the week when I have time to see if there is fuel coming through or not - thanks for the tip though :y
