Thanks Paul for directing me here. Could anybody help with this problem with my MV6 2.6? The car runs fine, but occassionally when I go back to it it turns over but does not start. 10, 20 or 30 minutes later it starts and is fine againg for hours, even days and then the problem starts again. I have recently changed the oil cooler, and plugs. Could something here have been disturbed on the loom? Could it be petrol pump or immobiliser problem? Could it be the ignition key? I do not know where to start with this problem to be honest. i look forward to any feedback. regards Ronnie

Crank Sensor..

there are different models be sure you get the correct one..

[ronnieboy]

It could be I did remove this to undo the oil cooler pipes at the oil filter end. I would have thought that the crank sensor would either work or not work but my fault seems to be intermittent. I will have a look at the sensor tomorrow aswell as other parts of the loom I may have disturbed. Thanks for the feedback, much appreciated.

Agree with Cem it on it way out - I  had same thing.
Then a non-starter.  :-/

No mate they do fail and can be intermittent when they are on their way out...mostly brings up a code 19 (not sure of relevant code for the facelift) but again not always...but almost certainly...crank shaft sensor on its way out...

Thanks I will look to pick one up from my VX dealer in the am. are they expensive to fit, and yes it is easy to remove from the block, but is it easy to disconnect the other end loom side?

Easy enough to fit yourself

[ronnieboy]

Thanks Lee. I check the plug at the top end first make sure I havent disturbed it when I did the oil cooler. I  did have to remove the injector rail plug for the oil cooler so stands a chance. I meant to say on my last post are they expensive to buy?

[ngrainqey]

if its the square/rectangle plug then around 40/45 pounds and 78ish for the oval one (oval ones for later one)

[ronnieboy]

ok good news. I will post an update tomorrow with progress and hopefully problem will be cured. I would like to thank everyone for their feedback with this problem. Kind regards Ronnie
