Any peugeot experts?

[sharky55]

Long story very short:- 205 with an S16 conversion, engine smoking heavily, bore wear diagnosed ( by local garage not interested in replacing engine). Owner buys Citroen Xantia with same engine and promptly removes it from the car. New engine fitted and wired up but won't go. It's now my job to get it to go. The wiring in the car is rough and unfortunately none if it was marked upon removal. I have no spark, no fuel pump and a handfull of extra multiplugs. What i would like to know is,
1. Is the crankshaft sensor the only trigger for the ignition system?

2. Can anyone tell me if there is a choice of flywheels (ala rover k series)?

Thanks in advance

Can't help much I'm afraid but remember there will also be immobiliser issues in there as well.

Sorry for being Thick, What engine is it???

You could try on http://s7.invisionfree.com/ActivaNet there are a few clever dicks on there that know everything.
If you got spare connectors though I'd say that was your problem, My time spent fiddling, if you un plug some of them the engine dies instantly! (2 litre turbo petrol)

There is no immobiliser on the car and they got another ECU with the with the new engine. Swapping the ECU's made no difference. As for the extra plugs, the owner is adamant that there were unsed multiplugs since he got the car. A wiring diagram would be the answer but no one can tell us what the original S16 loom came out of and i've since been told by Peugeot there is a multitude of choices!
The engine is a peugeot S16, a revised version of peugeot's MI16, basically a 2.0L 16V version of the TU engine (i think)

So it's the normally asspirated one then (weird that cause it seems to be the done thing to rip the engine out of Activas and stick it in an inferior car!!!!!)

It's a bit of a strange one about the imobiliser, 90% of Phase 1 Xantias had keypad imobilisers in them, and as far as I know the phase 2 had imobilisers in the keys.

I'd go to a breakers yard (the type that has the cars still together, the pick your own type!) and go and have a look, I know mine has a few spare connectors, off the top of my head,one under the Rad, one on top of the gear box and one by the cam belt, but our engines are a tad different!

Peugeot wiring is never what it seems.
I have done 2 205 MI16 conversions and both went differently.

My advise would be to recheck all wiring is going to where it should be, dont assume plugs are like for like.

Still an XU lump, but has a cast block not alloy, It was fitted to the last of the MI16's.

I made no assumptions when wiring it up (being the second person to do so), i repaired an engine section of the wiring loom on a 405 years ago which had me tearing my hair out (5 green wires 5 pink wires 5 white etc etc). If there is no immobiliser on the car and the last engine ran i can't see any reason why this one shouldn't run. How does the immobiliser work on a pug/citroen? Does it just cut fuel & spark or does it cut the power supply to the ECU??? There is another sensor on the end of the inlet cam like a phasing sensor but when you remove it i can't see a reluctor ring or anything- any clues?

I dont know much about the later engines as i havent had much to do with them, and i prefer the 1.9 anyway. The sensor you mention may well be a phase sensor of some sort as the S16 engine runs a coil pack instead of an empty dizzy on the 1.9, perhaps it picks up in a different way?

Pug Immobilisers are done in different ways, keypad or keyfob. The former is obvious but the latter may not be so easy to distinguish. The code would be stored in the EPROM in the ecu and a transponder near the ignition switch would pick up the code from the keyfob and compare it to the one in the ecu.

Ive got used to Pug wiring by now, some wires have the codes written all the way down it, others on the ends only, and others dont seem to have any or have a different code altogether on the other end! time to get the multimeter out

I had an MI16 conversion on my 205 back in 1995/96. I didn't want the hassle you're having so I opted for twin 45 carbs.Not sure if this will completely resolve the problem you've got but it is worth considering.

I think this thread is a few weeks old...so et us know if you've made any progress
