Sometimes I don't get the click, and start with just compression and 1/3 - 1/2 pedal. Mary (210,000) is a daily driver, Martha gets out once each week (290,000).

Know How! But it's not too hard. You need to grind off the top of the
connection to the contacts to get the wire and connector off. With the top
ground off it twists off easily and will leave a little stud. Discard or
recycle this. Remove the contact on the other side with pliers. Bend the
wire

to match and solder. Easy. You will need then to put a fuse and relay under
the hood and will have to do a wire run up to the modified relay which is just
a

connector to the glow plugs now. You will also need small wire into the
passenger compartment and a switch. Lighting the glowplug light would be nice
but I don't know how to do that yet on the late models. I know on the under

dash relay system.

You answered the question - How.  But what I want to know is why?  I have been through a series of 240Ds, 300Ds, and 300SDs and haven't seen a reason to change anything.

I had the same problem with a 240D, even did a valve job.  Checked everything, very hard to start but ran great once we got it running.  Never did find the problem.  We cut it up to put a front end on another car after it was sideswiped and we cleared enough insurance money to make it go away.  I wondered if the fuel timing was off, but I think I got it right when I replaced the head.  Never did figure out the problem.

I can't say I'm surprised.

Both Saturday and Sunday we made the 100 mile round trip trek to Cedar Hill , where my car has been sitting in the shop for more than 4 months.  We work on it when we can. 

First we ran all over town to pick up the transmission filter kit, air filter and fluids.  Of course they couldn't be at one store, no, we had to go to three different places. 

Kevin bent the CPR to where it appears it will work now. That was a challenge in and of itself.  We got everything else (possible) hooked up...as far as we know, poured kerosene in, no leaks, but a lot of gunk came out.  Filled it up with new oil & trans fluid.  Kevin put water in and what do you think???  Of course he saw a leak at the thermostat. The gasket crumbled when he barely touched it.  NAPA DID have one in stock, $10 cheaper than O'Reilley who would have to order it,  but it was right at 5pm on Sunday and they were closing!   Arrrrgh.  NO we didn't get to start the car this weekend.  I think Kevin was pushing hard for 2 reasons...it's Valentines and he's getting ribbed a lot from the guys at work for how long it's been sitting...the same ones that have yet to offer to twist a wrench, but they offer plenty of hot air.

We still have the challenge of the exhaust to deal with. Looks like it'll be next week before it'll be road ready.  We're getting closer.  I think there's also something about needing to by pass something to do with the turbo.  Mark in TX what was that?  And how does he go about it?

[diesel_mercedes] Hard starting 83 240D. Glow plugs are new. Modification included.

 

I replaced three glow plugs before I noticed the old ones were good. The
symptom is cranking for a long time. A little life. Then slowly starting with
a puff of black smoke when she really starts up. This sounds to me like I just
started with no glow plugs. The car starts better with no fast throttle and no
throttle until it coughs. Just like starting with no glow plugs. I measured
voltage at the glow plug and it's about 10.5vdc. Should there be that much
sag? I'm thinking about taking an old relay and plugging in to the harness and
just doing a manual hard wired glow plug cycle and just count to ten. Using the
old relay attached to a starter cable. That way I know the 12v battery is going
directly into the plugs. I suspect that somehow I'm not getting big amps to the
glow plugs. I have good compression but I don't know how long that will last if
I keep starting hard on vegetable oil. I did a diesel purge and that didn't
help. Any other suggestions would be appreciated. Lawrence Rhodes.
