Today was a good day although it was cold working out there. I remove the lift pump from the turbo IP an checked it with my thumb it definitely was working well. I cleaned it up a little.

Then I removed the lift pump from the 80 IP That was diffiicult to say the least since those 10 mm nuts are hard to get to and they are cold.
When I got the lift pump off I could see that the pump was not funtioning at all since the plunger was stuck in the pump.

It is really amazing that the engine would run at all with a non functioning lift pump. I went 3 or so miles with no lift pump, amazing. Anyway, after I put the one that worked on and hand pumped up the pressure, the car ran again beautifully. I was brave enough to drive to the store about a 14 mile round trip. No problems with the engine at all, it runs great now. Hopefully it will continue to run great for a long time. I put more diesel in the tank diluting the svo that was in there and there was no change in the way it ran at all.

My problem now is the vacuum line to the tranny, its shifing hard so I need to figure out how to get that back together the right way.

I'll be putting the NA engine back together and playing with the turbo IP on the stand till I can work out that problem with the rack or what ever it is, but at least now I can go and get what I need.

I'm very satisfied with the way this 83 300SD is running now.

Barry what ever happened to the car you bought that had the problem of stalling every so often? Did you locate the problem?
