Try the engine control relay, common enough on these.

It could be the glow plugs.

Yeah they can go on the spot, happened to a Citroen xsara I owned at least twice. A lot of the problem is if you don't let the amber light go out before starting the engine.

I meant the amber light that comes on when you turn the ignition that needs to go out before starting.

Get someone else to turn it over while you look at the exhaust. Gray smoke as it turs over means you have fuel and likely a heat/compression issue. If no smoke you're not getting fuel.

Another problem common on these is the ecu giving up due to water.
It's situated under the wiper on the driver side. Water gets in and corrodes unit.

Might be worth taking a look to see if it's dry or wet and the general appearance.

Time to get a wiring diagram and do some checking to see why that diagnostic socket is dead, if it is dead.
