Yep, it's always a GOOD sign when the first aid kit hasn't been used!

Mine is missing entirely so I presume one of the previous owners of the car needed just about everything in there.........

Well, we have to have a picture here at some point soon.

From your initial inspection, it is beginning to sound like fuel delivery issues may be why its not running. And it may even be problems before you get to the injection pump. There was someone recently who was selling the hand primer pumps on EBay for about $29 - search on "Mercedes Diesel" to see if more are listed.

Your list of tasks looks good. You may want to assess the condition of the radiator yourself before you go to the time and expense of taking it all out and having a radiator shop refurbish it. After all, there is a chance there is nothing wrong with it. Hopefully they kept good antifreeze in it, and when you get a chance to look in the top with the hose off, it won't be too corroded. This is the one thing you have listed that can cost some bucks.
