Wierd Starting issue, wont start off for 5-10mins
« on: 28 January 2008, 15:37:03 »
Thanks to everyone re my gearbox issue, new selector switch has resolved my issue.

But now have a strange issue where if I go somewhere and turn the engine off for a short time, it wont start again! leave it for about 20mins and it starts...... Breakdown people thought it was an immobilser. But I dont have one i thought. Alarm at least was torn out by the police, (x police car not a raid on my car!)

Did it again the other day at blockbusters. Wouldnt start, would kick into life. left it and then started no bother. wierd....

Sounds like possibly a failing crank sensor to me. Read the fault codes from the engine ECU and see what you've got.

Just a thought, when you say it won't start, it is turning over on the starter motor, but just not firing, correct?

.. or is it failing to turn over completely?

spare sensor? I only just heard that it existed. How much these things cost then? roughly?
Might take up on that offer 'TheBoy'

Mine was roughly 40 quid on trade club. Might find them slightly cheaper on ebay but make sure you identify which one your car needs as there are a couple of varieties.

However, get the codes read first. It just may be something else.

As per PM, happy to tech2 it, but a paperclip is cheaper if you want to try yourself ;)

If you have a 19 stored, get a new cranksensor.  Plastic type (likely for yours) about £40 + VAT, metal type about £20 more
