Hi Folks
Never had any problem until new Bosch fuel pump recently fitted (slanted wiith rubber primer on top), but big problems starting.My mechanic had to reseat the seals and change plastic pipes to pump since they were taking in air to injectors.
Problem now in cold weather, vehicle very very difficult to start in mornings.When I check the primer first thing before starting engine, it fully depresses until "full". Is this normal after standing idle overnight, or should primer be always "full" after overnight flat standing?
Also, when finally starts after twenty minutes, it seems to stutter on two cylinders , then fires with greyish/white smoke from exhaust polluting the air. When running, goes great, starts first time when engine warm/hot.
It is only after engine cold that probems occur.
Any views for a non-technical person, please.
Thanks,
Ric

R.A When a diesel fuel system is working it is working under negative pressure,so that when you leave it overnight it sucks in air through any cracks or bad seals Can I suggest smearing grease on anywhere you think might let in air and if this improves matters that is where your problem could be H.T.H. tonyh

Thanks for response, I am doing as you say, and will let people know if it works so it doesn't happen to other folks, especially in cold weather.
One point I noticed, the two plastic pipes leading to the fuel pump do NOT have any form of metal circlips holding them tight, they are just pushed as far as they can go! When the diesel engine is running (and obviously shaking), one of the pipes is slowly coming away from the fuel metal pipe it sheaths (if that is the term), and I have to push it back in place.
