More like crank sensor, do a pedal trick to be sure 

Does a dodgy crank sensor cause engine "cut out"  as well as difficult/non starting then ?

Also just checked service history . . . GM crank sensor replaced by VX dealer 35k ago 

Al - deffo classic symptoms of failed crank sensor (not cam sensor) - failed crank sensor doesn't always throw a fault code though   best regards 

[albitz]

Al - Ive got a known good one here you can borrow until you get a new one, if you can get up to see me at work tomorrow or Thurs.

Soz, late to this thread 

Certainly sounds the standard, classic symptoms of a crank sensor on a GM V6. This is why I *always* carry one in the boot (which is a slight lie, as only one of the Omegas has a crank sensor in the boot ).

If you reroute the cable, you can change it in about 5mins, in the dark, in the NEC carpark ...   ...as long as you have a jack

[albitz]

I have changed one without a jack (n/s wheel on a kerb) but I was a bit slimmer then.

Yeah, I reckon with a non lowered car, and a decent kerb, its doable

[Big_Al]

I am thinking that maybe I should have the new crank sensor  ready . .  .

 but wait until I get the same problem again & then change it straight away 

With suitable jack & tools carried at all times 

That way it should confirm it was the faulty crank sensor  . .  .  shouldn't it ?

Also is there a pic anywhere of the recommended "new cable route " for the crank sensor ?

Had a quick search but could not come across anything

Am still worried about the TC light coming on ,the radio turning itself on & the date & time  in info display resetting to 1997 & 00:00

just before this "breakdown" though    would that still be crank sensor related ?

found the pictures for this now

I'd just get it done because it's very random as to when it goes 

[the alarming man]

as webby says very random when they go do you really fancy changing one on the hard shoulder of the M1

Good point Mark . . . but my reason for that approach is to prove it is a faulty CS. As this fault has not occured for year now until last week & once again the car is now starting on the button & running fine 

But I will fit a new one before we head off to Burton though.

I can guarantee you it is likely to fail at the most inoppertune moment, in order to cause maximum embarrassment.

In my case, just outside Dijon, on the motorway. French law dictates you have to tell the authorities, who then arrange towing away, and you end up spending the night in a git miles from anywhere, and then...   ...oh, no, thats another story

I'd highly recommend changing it at the first opportunity.

Will do then  . . . .

Al the Elite you bought from me had a re-routed crank sensor on it - if your neighbour still has it you could have a nose at it
