Hi all

I am currently trying to revive a 406 1.8 petrol estate. I have done all that was needed with the help of my mechanic friend but we have hit a wall.

IT WILL NOT START!!!! We have changed the fuel filter and checked the fuel is flowing correctly. We have also changed the plugs but still cannot get a spark.

I have the pin code for the imobaliser which seems to work fine so is there a magic trick i'm missing???

The car was stood for about 12 months and the battery was completely dead so not sure if that has done any damage.


Any ideas would be gratefully recived.

many thanks,

Does the immobiliser keypad show a red light, then a green one once you've put the code in?

I seem to recall someone saying there's just one coil pack that feeds all the plugs on 406s... could be that, or a ground/power near it?

Sounds like the following, what James on here said:

if your car is refusing to start and the keypad/immobiliser is functioning accordingly then most likely the TDC sensor, or Top Dead Centre sensor is faulty, its often called a crank angle sensor, crank position sensor or engine speed sensor, it basically informs the engine management of the position of the crankshaft so it can time the injection and spark correctly, what usually happens is the thermostat housing, positioned directly above the sensor developes a leak and shorts the sensor internally rendering it usesless,

cheers gents. I have a auto electrician coming to look at it on monday.

will post how it goes.
