The car now stumbles and dies on first startup attempt. It doesn't seem to matter if it is warm or cold. On the second (or third) attempt it stumbles but starts and smoothes out. I'm going to start with the fuel solinoid. I suppose glow plugs would be in order if I'm going that far. Are there any other starting issues I should know about? I'll keep searching.

Mike thank you for your info. I cannot tell you how much those part numbers mean. Your dead on with that #32 o-ring. Seems strange to leak there but I saw bubbles coming out of that spot. It's possible the fuel originated from a fuel line leak on top of the fuel solinoid. That might then indicate an air leak? (bubbles). Is that o-ring under positive pressure? I'm pretty sure it's simplly leaking fuel at the spot I have identivied in the picture. I see the fuel lines but I'm not up to speed on the direction of flow of the fuel yet.
