Hi
Car is a 1999 V Reg scenic RT 1600 Petrol.
Problem is usual as in car was stopped then when tried to start, nothing. Occasionally tries to start,will fire then cuts out. Have checked for spark but nothing there, have changed TDC sensor for new but no different.
Immobileser light does not go out when unlocking with key fob and when you turn ignition on, the speed of the flash increases. Have spent most of the afternoon reading numerous articles which seem to relate to IR Fobs, mine is a RF Fob. Tried using the C/L buttton on the dash to slow it down but no effect thinking could maybe get the Immob code(not sure where as no code inside key fob) and enter manually.
So now sat here scratching my head on a Sunday evening wondering what next, so any help would be gratefully received.

I've tried to edit out all this IT technobabble but it won't go - sorry!

It does sound like a problem with your immobiliser. I presume you've tried locking and unlocking with the key instead of the plipper? The trouble with electronic faults like this is that only dealers have the equipment to sort them out, and even if you are skilled at DIY you still can't solve iit.

Hi

No haven't tried just using the key in the door but will give it a go TOMORROW.

Tried a new battery in the key but no good at first then after locking/unlocking a few times the engine fired but only for a second or two then stopped and would not fire again. Gave up again after a while.

Still baffled!!

If the engine briefly runs and then stops as you describe it . If you are inside the vehicle and the immobiliser is "set" gh inactivity, you need 2 clicks of the button to "open" it so that the red light is on constantly and starting can proceed. If the red light islashing, the immobiliser is "nd you are out of sequence (by one click). You therefore need to one more click to get the red light on constantly

If the engine briefly runs and then stops as you describe, it seems like the immobiliser is in operation. If you are inside the vehicle and the immobiliser is set through inactivity, you need 2 clicks of the button to "open" it so that the red light is on constantly and starting can proceed. If the red light is flashing, the immobiliser is set and you are out of sequence (by one click). You therefore need to do one more click to get the red light on constantly .
