My Partner has the 1.9 diesel, not common rail. a 2002 model.
For over a year now it takes forever to start in the mornings on a new battery but fine the rest of the day and runs well otherwise and recently passed MOT with perfect exhaust clarity.
I have checked plugs individually. Changed plugs but still the problem. It is not the relay as it cranks through 80 amps for 30 seconds after the light goes out. I have a relay bypass but still the same.
The wax cold start plug doesn't work but even when I set the timing at maximum retard it still doesn't go.
Cold start doesn't help at all.

My daughter has a 206 with exactly the same engine and also a non working cold start but that engine starts instantly at minus 10 degrees

Any thoughts?

A lot of them are like this I have 2 1 starts great other cranks a while fine once started so I just suffer it !

It is a common issue some say it is wear in the pump meaning the pressure is too low to crack open the injectors

Wax stats rarely work and when they do it only helps it run smoother when cold

I'm coming to the same conclusion. As it is such a great workhorse I'll run it till it drops. One final check with a leak off test then just live with it.
If it had been 10 years ago I would just have swapped the pumps.

How many miles has the engine done?
Poor compression will cause exactly your problem, start by checking the valve clearances, they tighten up with age, and eventually the valves don't quite close which means it's almost impossible to start when cold.
All this is from personal experience with a 1.9d.
On mine I reset the valve clearances to the correct figure and the cold starting improved immensely, the engine went on for many more miles until a ring broke.

It's 160,000 mls so not that much for a 1.9.
Thanks for that idea. Never thought about it. Worth a try.
