Then engine was changed, i think its the mechanical pump type ,because I couldnt find the ecu , normally located in the engine bay. The engine management light do not come on the dash board and nor does it weven turn over.

But the key is a transponder key.
I was told buy a friend of mine that the alarm relay may be missing, phone up peugeot they dont seem to know what it is .

ay help appreciated

Dont know If anyones experienced this
I changed the engine on a pug 306 1.9D T reg 1999
its got a transponder key
Nows the engines back in I dont seem to get any engine management lights I get the normal indicators lights etc. The engine wont even turn over . Has it got anything to do with the ecu being locked or something ?
Any help

cheers

Have you changed just the engine block or have you changed the ecu as well?

Are all the plugs attached? Does the 306 have the same plugs behind the passenger side headlight as the 405? There is one big round plug and a single spade. This is the connection to the starter as I discovered recently after changing a 405td. Does the engine have an ecu or is it the traditional mechanical fuel pump?
 
sounds like battery leads mixed up

Hello,

I forgot to mention the headlight do come on

Well, relays' coils & bulbs have no polarity. Perhaps a steal-lock problem.

Hello,
what do you mean by steal-lock problem ?

Sometimes, the ignition barrel (including steal-lock) suffers from heavy currents needed by starter. It's common on heavy mileage 205s. Report to the group's archive, it was discussed at least 20 times.
 
The cars only done 40k miles.
I was wondering if the relays are put in wrong under the dash would it stop the engine from even turning over !!!

Perhaps. I can't give an answer, I've got no certitude about that... Indeed, automotive relays have a pinout that makes it impossible to put them the wrong way. IIRC (I don't want to remove one of my car's relays), the pinout is like that :

Where there are one supply, two contacts two positions (DPDT). Please guys, correct me if I'm wrong ! My point was, the (generic) relay coil has no polarity, but automotive relays could be different (like, why not, a diode in series with the coil (I can't imagine why)). A badly plugged relay could be a source of problems (no contact), as well as a burnt relay.
