Anyway crank sensors are cheap..

are they?  I thought they were c 50 quid give or take..  for me that is a lot for just experimenting without knowing it will fix the problem.

Anyway surely the paperclip will show up the problem if its crank sensor..?

Here I buy for 35 £ ..This is the most critical part that will let you with a 1.6 tons of non moving metal in the middle of the road..

if you dont like surprises and to pay for the carrier truck its better to pay for that I think..

Also note that even without any problem I think changing this sensor is a preventive action..If you go to the service with car on truck the prices really change.

I agree with carrying spare in car (after I broke down in France), but wouldn't change as preventative measure, unless you were getting code 19...

Did the paperclip test and I am only getting code 31.
I believe this is 'no rpm signal' - don't you always get this when the engine is not running? Obviously I can't run the engine to see if it goes away.
Any help?

I searched the net :

here are the answers

note that my money is on the crank sensor still..  By the way what was the mileage

31 normal.  if you can get car to run for a few mins, retry test with engine running....


may be time to check plugs to see if running rich/lean...

[AndyT]

No chance - it will not run, just fires and dies. I guess the plugs will be covered with all sorts of rubish after so many attempts to start.
When this problem first started, there was no EMU light showing, the usually smooth idle was just a little rough, with the idle speed rising and falling. The only time I saw the light come on was when travelling at speed shortly before it stopped for good - and then the light only flashed on for a second or two.

can you gently peel back cambelt cover, ensure cambelt still goes round....

[Nickbat]

As others have said, I reckon the crank sensor is the most likely culprit. Around £34 (see other thread http://www.omegaowners.com/forum/YaBB.pl?num=1188504203) and relatively easy to fit. It's worth doing in any event because, even if it hasn't gone, it is likely to do so in the not-to-distant future (especially given the mileage).

AndyT - can you update profile with location? Are you near me?

[AndyT]

My location is Essex - too far away from you unfortunately.
The crankshaft sensor theory makes sense so tomorrow I intend to remove it to see which one it is (seems there are 2 or 3 varieties) and then I will order one up from one of the websites and give it a try.
I will post the result.

Andy, you don't need to take off the whole thing to tell which one it is. Disconnect the top end of the cable and take a look. Some have a square connector, some have a slightly oval connector. If you want you can take a photo and post it here and someone will identify it.

Good luck!

  ! ! FIXED IT ! !  

I am almost embarrassed to admit what the problem was ! One of the air ducts from the multiram to the throttle body had partially slipped off at the multiram. Not easy to see unless you are looking really hard. Put it on again (firmly) and it started straight off. Whilst it was running, I removed the duct again and the engine stopped immediately.
So many thanks to all of you out there for your assistance and suggestions - its great to know that when problems do occur there are people who are willing to help.

Andy T

Oh - and thanks to Mr Haynes who in his manual suggests that you look for air leaks if you have this same problem. First time ever in my experience he has been right.

Cheaper than a crank sensor!
