Anyone clued up on peugeot electrics? - Fozzy - 15-08-2018
A friend has a 2001 406 that wont start. It has power to all relevant systems, ecu, fuel/ign relay etc. It is getting fuel to the rail. But it still wont start. Im thinking its a lack of spark, but it has a coil pack, so its difficult to check the spark at the plugs.
Anyone know what i could check next

How much you would get for it at the scrappy :kiltsmilie:

Pete, excuse my ignorance but why a coil pack makes it hard to check for sparks

Yeah, pete all you gotta do it pull the plug out whilst still plugged into the HT lead and it will still show a spark...

Because there are no HT leads. It is a coil on plug setup. The coil pack earths through the head, so it needs to be bolted to the engine to work

In that case I would just run an earth lead from coil to suitable ground point, it does not have to be a heavy connection as it only produces low current. then earth your spark plug to check for spark.
Fingers clear of course

Problem is i am certain there is no spark already. DOing this will just confirm what i already have an idea of. I just have no idea why there is no spark. There is power at the relay, as it is allowing the fuel pump to run.
I guess it could be a duff sensor, whi9ch if the ecu cant read it wont allow any spark, im just wondering if someone could confirm

I hear wot you are saying, sounds very much like a duff crank sensor not allowing switching, I will have a look on my works laptop to se if I can find a wiring diagram for the ignition circuit...
