Vectra Diesel 2.0 Starting problem

[Slick]

and if it`s the seals why doesn`t it start after 2 seconds after I stopped it ? I can`t explain this. If it wouldn`t start after a while and started every time after I stopped it I would think like you but in this case I don`t...

Is your car parked on a hill? i know with mine if i park it facing uphill it wont start it just turns over and over! but when i point it down hill it starts after turning it over for a while,

Silly i know but the vaux garage told me its a common thing with diesel vectras!

just an idea

depends where pistons settle on its final stroke, if it draws air back in...

ever turned a car over by hand and not quite turned enough on its stroke.... wants to go back ...

if u unsure etc, and cant do the vac tests take it somewhere that can pal.
