we managed to get the car some shelter this night and this morning it would start after quite some cranking...
as far as i understand,the glow plug itself shuts off when the glow plug light goes out right?, so what i did was turn on an off the ignition 3 times before actually starting, waiting each time untill the light went out, assuming that this would cause the glow plug to heat up more... is this good practice or will this make no difference?...
the car still require quite some crank time so i don't think it would have started had it been outside

outside temps are about -8°C for the last two weeks, that's a bit colder and longer than what we're used to.

i'll have a look at the plug and the oil thickness

searching the internet it seems this is a common issue with this car and other diesels of the same age. one forum post talked about fitting a "hand primer" or a one way valve in the fuelline, not much details where given as to how and where this should be done but the poster was fairly confident that this would cure the problem.

it's cold enough the hoses/seals may contract to the point where the injector pump looses it's prime?
you seem to refere to the same problem?

so is it really a combination of the temps and the fuel system design that enable the fuel to flow from the fuellines and the pump (wich i believe might be mechanicaly driven by the engine?) is turning to slow to get the thick fuel back
i've towed the car to a start a couple of time as that goes really well, and once it's running it doesn't seems all that bothered by the weather.

so perhaps some sort return valve or simple pump could help me there, but how should i go about this?

it would be nice to have a winter "button" or trick that would get the car going anyway.
