306 HDI Intermittently not starting.

fuel filter? got warter in it?

Glow plugs?

If you get a load of white smoke & a brief period of rough running that's the most likely cause (if you don't t's the cheapest thing to fix!)

Have you got any MIL lamp flashing or remaining lit, or not coming on initially with the key? There have been main relay issues periodically with this engine.

If no MIL lamp irregularitys, then check the connector on the Rail pressure transducer-ensure the conductors are clean and oil free. This is the next most likely cause.

Tim..

The Hdi, along with nearly all DI common rail engines don't use the glow plugs at all unless the temperature is very low- in the case of the HDI, the threshold is 4degrees.

Tim..

I will look out for the lights the next time it fails to start., they and it are both behaving at the moment.

Is the connector on the Rail pressure transducer fairly obvious when the acoustic cover is removed from the engine?

I ask because there isn't a workshop manual available for the 306 HDI. (unless someone knows better?)

Thanks

Brian.

Yes, toward the end of the rail on most varients of the HDi, on the pressure pump on others (usually 206 engines for some reason)
