can anyone please advise me , what is the solution to this problem : I drive an N reg peugeot 106 normally a good faithful runner, serviced recently. However a few weeks ago one day it wouldn't start. Managed to only with the aid of some quick start spray into the air manifold. The car worked fine for a few weeks only to suddenly a morning not start, again only aided by the spray,does anyone know the cause/remedy ?

Petrol or diesel?

Is it turning over or not?

Does it only do it when cold?

Does it turn over slowly?

thanks for responding Davepoth, the engine is diesel, before starting key in egnition, wait until yellow glow light on dashboard goes out, turn key all red battery/oils on , car tumbles but wont turn over , if one continues the battery will start to fad but she wont turn over.. the weather doesnt matter, the times this has happened has not been really cold. thanks again for replying have you any further ideas ?

Do you mean it turns over on the starter but doesn't fire up?

If so, this sort of problem is often a glow plug fault on diesels but knowing these engines, it's more likely to be tight valve clearances (tappets), if it's inconsistent in its failure to start.

Thank you Oakdale, yes it turns over on the starter but not fire up. I will explore what you suspect. I am not mechanical trained, is there any other relevant points I should also be considering?

N reg diesel...Electric fuel pump? It could be a tired battery/alternator I guess, not able to crank and pump?

Sounds like key transponder issue.

1. Turn key to pre heat glow plugs
2. After heating turn key right off
3. Turn key all the way to start engine in one movement

4. If the above doesn't work give the steering column cowl a whack underneath, then repeat steps 1-3.

I had this issue on my (petrol) 106 and the above method was recommended after I had starting issues, apparently it's a known issue.

It won't be a transponder or immobiliser problem if it starts on easy start and then continues to run.

Good point, I didn't read the OP properly!

It sounds as if the glow plugs are not working,they may be just "past sell by date" or a known wiring problem I`ve seen on old 106 diesels.Have a look down on the n/side of the radiator and you will find a couple of egg shaped multi plugs,one is for the glow plug loom.Unscrew the ring and pull the plug apart.I`ve seen many with "green" corroded connections and some burnt and melted.

Old Merc thanks for the suggestion, my mechanic assures me he has ruled out the glow plugs, however I will ask him to double check , thanks again.

There is another poor COLD start problem on old 106 TU diesels but not so common.With age and mileage the valves "sink" in the seat inserts causing the valve clearances to disappear giving the engine poor compression.

I think you also need to check the waxstat cable is operating the diesel pump lever.
This is the coldstart facility as I remember
