Went to use the car this morning, it laboured a little bit and then was ok. Went around the corner to the paper shop and got back in. Car will turn over but won't start?
Spanner light is now flashing on pre ignition.
I will try and get hold of a fault code reader later - but what could it be?
-
Try this and report any codes back here :y

my money is on the crank sensor being duff
-
Easier than any of that guys - sussed it!
I dropped the keys when I got out the car and disloged the immobiliser chip. Put it back and it started!
Still, worth bearing in mind if anyone reads this as it could be as simple as that.

good one. :y

DTC,
Searching for similar problem to the one I have and I think this could be it. About 2 weeks ago I couldn't start the car. It was spinning over well and was just not firing up or even trying to fire. I did a few checks and noticed no spark at all and thought it could be the immobiliser. I recalled that my son had gone to get something from the car earlier and had thrown the keys to me. Although I caught them they would have suffered a bit of a shock load. A few gentle taps of the key seemed to fix the problem and no recurrence until today. I can't recall dropping or any rough handling of the keys at all today and this time gentle tapping didn't help. I even took the key apart to see if there was anything obviously wrong, but could see nothing obvious. Fortunately the spare key I have then started the car first turn, which was great, but then just to confirm that the cause of the problem was the key I tried to start it again with the original key and it started no problem, so now I'm not sure.
Is this likely to be a key related immobiliser problem. If the chip can become loose and be refitted can you give me any pointers as to what to look for?
Any ideas would be appreciated.

as above really, possible impending crank sensor failure.

Nice easy fix,glad you got it sorted :y

Common problem .. the "transmitter" side of the immobilisor (transponder) is a very small chip in the "horseshoe" part of the key ... be very careful when you take the key apart as if you lose it you have a serious problem. This chip should be securely situated in a small cutout designed to take it .. but they come loose and end up moving around inside the key.
If in the incorrect place the "reciever" part of the immobilisor (on the steering column) can't read it ... so assumes it is not the correct key and prevents the engine starting (EML light flashes continually whilst cranking)
Solution is dead easy .. if the transponder chip is loose .. a small dab of superglue to hold it in place, reassemble key and life is great .... :)
Seriously .. it IS that simple !!!
HTH :)

The clue was in your first post - Car will turn over but won't start?
Spanner light is now flashing on pre ignition.
- shows immobilisor problem.

I checked my key chip and it is in place and well secure. It is retained in a recess, so unless the key came apart I can't see much scope for it to move. I thought possibly internal damage to the chip could be a possibility.
I didn't really notice the EML flashing while the engine was cranking. If it happens again I will take note. If there was a fault it hasn't left a code other than the code 31 - Engine RPM signal (crankshaft sensor) no signal, which is always there when the engine is stopped.
