Thanks for the replies......And sorry for the long story below!

Yes, my car will fire up immediatly, it is just very rough and smokes. I do wait until I hear the relay click before I actually start the engine.

I'm luckly enough to be able to park the car in a garage, where I keep the temp arount 55 to 60. But it is parked at work during the day and the tempature has already gotten to just under freezing.
I'm using either 10w40 or 15w40, I forget which I used last, but it was within the last two weeks.
The battery is only a couple of years old and cranks the engine over quite well.
Changed both fuel filters with the last oil change.
I wouldn't know about algae in the tank, but there is no off odor to the fuel except diesel....which if course is not an off odor!
I have a block heater but because of the garage don't use it. Electrical hookups are not available at work.
All the lines look fairly new, no signs of decay.
You have me thinking about the bubbles in the small fuel prefilter, when I was running the engine last night I believe I did see lots of bubbles. Maybe I'm getting air in the fuel system somehow? I will look closely at that this evening.
I have not checked the compression. But I can tell you that I have had this car for at least 5 years up here. And it has been a daily driver all the time. It has never failed to start in any weather at any temprature.
It sure sucks not being able to rely on new components....but I will check out the glow plugs.
I don't add much to the tank other then fuel. Through the winter I will put in additives, not sure of the names but will find out.
I've only used diesel purge once, maybe a year ago. I had planned on running another dose or two through the system.

I have recently changed the motor mounts, which had completly collapsed.
That made quite a change in how the car feels but mostly at speed. If anything it lets me feel more of the roughness at idle. I'm paying more attention to the old girl lately and believe there is nailing happening at at least one injector.

Pictures???? you mean actually wash and wax it so that I could even think about posting it.........I'll have to think about that!
