    Thank You, i need to know if there is a picture diagram, that shows where the vacuum lines and hose are hook up on the motor. that would be a lot easier for me. I know little about cars. i have to open the hood to turn the engine off, by attaching one of the vacuum hose to the line. Thank You

Rbbnsent: Let me see if I can help you.Fird, your vacuum lines are color coded if you look closely. As they age, some of them get difficult to differentiate from. One place where you can positively ID them, is where the line has not been exposed to the elements. That is where they have been inside a vacuum hose.
Ready?
Starting off, the vacuum line which shuts off the engine is a brown/blue line it goes to a diaphragm that has the fitting facing parallel to the pump body (runs parallel to the ground) Hook the line into the diaphragm.
Next, you have a vacuum hose which has a check valve on it.
Connect this one to the fitting which runs straight up.
There should be a white line near by. Hook the line up to the fitting just behind the one you just hooked up.
There should be a Black line going into the back of the pump.
Alright, coming off the vacuum pump, you have a fitting which should 4 lines excluding the vacuum source.
Now the vacuum source should have a check valve in line with it.
The following colors should be going into this "T"
White, white/blue, green, white/black.
Going back to the injection pump: Coming off the line which had the check valve, one direction is white/violet/brown and the other direction which heads off in the same direction as the front of the motor, is black.
The Black line coming out of the back of the pump hits a "T" which goes to a check valve and it hits another "T"
Coming off the side of that "T" is a white/green
I'm pretty sure, I have far exceeded the number of vacuum hoses which you found disconnected.
I hope I have answered you question thoroughly.
I happen to drive a Mercedes Diesel (81 300TD wagon) I love it!
Let me know how you make out. Mercedes Diesel are a specialty of mine!

    I will see what I can do about a picture diagram. HOWEVER,

    PRINT my instructions in BIG BOLD PRINT. Read it SLOWLY several times and then go out to the car, open the hood and if you follow my instructions, it will be a cinch. I use to teach on a substitute basis in night classes. I have found that some people I have taught have been intimidated by the picture diagrams that some manufacturers print and end up calling me.

    Trust me, try it>>>>>>>>>>>>I'll be here for you.......

The starters on the Diesels are pretty heavy duty so unless the bolts or a wire is coming loose I would rule out "going bad already" Other issue would be if you put in a used one 3 weeks ago.
Take note how the ignition feels when you turn the key, if you wiggle it and turn it slowly just right does it help ? The contacts in the back of the switch may be wearing out.
I hope this helps

Check your fuel pump pressure. You can rent a fuel pressure gauge from autozone and check pressure coming from supply pump. I bet its weak. Hope this helps.

neto 190D: You are asking about a vacuum diaphragm?
I'm going to take a WAG.. Your engine won't shut
down with the key?
If so, he is the way you find out:
In your injection pump, the vacuum diaphragm which kills the engine is the one which has the fitting pointing parallel to the ground.
The vacuum line which serves it is a brown/blue
To check the system, first check for vacuum in the line. Run the engine for a minute or so. Cap off the brown/blue line.
Turn the ignition switch off and then with hose in hand, uncap it and you should hear a hissing sound. If you have a vacuum guage, obviously, use it for the test, you need a minimum of 10 inches to kill it.
To test the pump diaphragm, you can rig a vacuum line to a known vacuum source close to the main "T". Run the engine and with the line connected to the diaphragm, connect it to the good vacuum source, if it kill the engine, the diaphragm is good. If you have a hand vacuum pump it would be more ideal, because you could check the diaphragm for small leaks.
If the diaphragm is bad, it is easy to replace on the pump.
The shutoff diaphragm lists for $86.00
Is my shot in the dark correct?
Even though I am a Nissan Master tech, I also specialize in Mercedes-Benz and specifically Diesels, so if you need help, I'm here. I went through a few Mercedes Schools and have been swinging Iron in Mercedes since the 70's
I might be a little more informative than the public library.
