Re: [MBZ] Cold starting issue - glow plugs?

[Curt Raymond via Mercedes]

Your block heater doesn't seem to work. If it did the car would start easily. 
Start by making sure the cable isn't munched. Just follow it to where it plugs 
in, damage will be obvious.

Re: [MBZ] Cold starting issue - glow plugs?

[Curt Raymond via Mercedes]

I've apparently had some summer fuel foisted on me. I've been using a new place 
that only recently started carrying diesel. We picked up my car yesterday after 
getting a new front wheel bearing and it couldn't get out of it's own way. That 
was at about 0F, it started okay but had zero power. Fortunately we only had to 
limp a few miles home. I put some Power Service to it and let it run awhile. I 
didn't get a chance to try it today, I was out chasing Bambi's dad but Angie's 
car did the same thing Wednesday and was better after treatment so I'm 
expecting good results.One car I could have passed off as water, two with 
exactly the same problem is bad fuel...

Below, -10, everything has to be right.  Fuel, Glow, oil, IP, Nozzles,

It is a good idea to plug in the block heater below 0.

On an Iron head engine, if you set stuck in the way cold while 
traveling, you can use a propane torch to heat the head and/or the oil  
pan (Carefully)
Way cold = below 0ºF.

Re: [MBZ] Cold starting issue - glow plugs?

[Curley McLain via Mercedes]

it helps.  That is part one of a two stage glow.  The second is to glow 
until the light goes off...or a bit longer, but before the relay times out.



Mitch Haley via Mercedes 
December 29, 2017 at 12:36 PM
I wonder what a single long glow would do.
Turn it to 'on', wait until the relay clunks off, then turn it to start.
Of course, it helps if you can hear the relay...

Kurley wouldn't last a day here.  20 above, but it's damp cold that only
those who live inside the beltway can deal with.

Seriously - I did attempt a triple glow start this morning, sans the block
heater.  Voila - started much more easily than yesterday with a preheated
engine.  My Achilles Heel will be a balky starter for wheni t gets REALLY
cold.

I also will test my GPs as a precaution.

Thanks - good questions.

If fuse were bad it would not start Period. Same with the gp relay -

Might need a valve adjustment I do a lot of stop and go driving. Maybe
this has hastened the valve clearance tightening?  YES

Battery is strong. I did not try lengthy afterglow - that could help.  
NO WAY TO DO AFTERGLOW ON A 85, unless you cut the violet wire or take 
the pin out of the plug.


Perhaps tomorrow I will try to start w/o using the block heater but try
after-glowing instead.  DON'T BOTHER,  TEST THE GPs and RELAY!

Dwight wrote: *My 79 240D would start at 4F with no heater using the

TWICE.  Third time, crank when the light goes OUT!

Low probability might be an air leak in the fuel system that allows 
air in so the injection pump looses it's prime. ;-)


I'd start with the preglow system as already discussed, keep this idea 
in mind if that route doesn't solve the issue.


Valves adjusted recently?

December 28, 2017 at 3:27 PM
On my W123 300TD, I am having a hard time getting it started when the
temperature dips below 20 F despite the car being plugged into the block
heater. It takes 2 minutes of multiple glows and attempts before I can get
it fired up. Once I get it started the engine runs as if it were 
preheated.


Question: Does this sound like a glow plug issue? Do the plugs wear out or
simply fail? If one is dead will the other 4 start the car, albeit
laboriously?

Happy 2018 to all,

Thanks - good questions.

Primer as the updated black cap.

If fuse were bad it would not start  Period.  Same with the gp relay -
would turn but wouldn't fire.

Might need a valve adjustment  I do a lot of stop and go driving.  Maybe
this has hastened the valve clearance tightening?

Battery is strong.  I did not try lengthy afterglow - that could help.

Perhaps tomorrow I will try to start w/o using the block heater but try
after-glowing instead.

Re: [MBZ] Cold starting issue - glow plugs?

[Curley McLain via Mercedes]

Try afterglow.  It was enabled in the later 603/6 engines.  cut the 
violet wire in the small cable to the glow relay.  That will enable the 
afterglow.  On the push pull glow, I always disconnected the cable form 
the IP and put in a separate shutoff.  That way on really cold days you 
could manually do an afterglow until the engine was firing evenly and 
normally.  I could aldo lock the ign and steering; take the key and 
leave it idle in the cold weather.  (Doors locked)


I always thought the elegant way to enable afterglow on the early 60x 
engines would be to put a switch under the dash and cut into the violet 
wire somewhere near the fuseblock.  THen you could turn the switch off 
for afterglow int he winter, and on for no afterglow int he 
summer/spring/fall when it is not needed.

Re: [MBZ] Cold starting issue - glow plugs?

[Curley McLain via Mercedes]

I never had any trouble down to 0 to -10.  BUT I was always careful to 
get winter fuel.  One time a truck stop foisted summer fuel on me 
without notice.  That caused problems because it was way cold.  Once I 
got enough kerosene mixed with it all was well, but since I had filled, 
I had to put in as much K as I could 3 times before it straightened out.


Below, -10, everything has to be right.  Fuel, Glow, oil, IP, Nozzles, 
advance, timing, valve timing, valves...

It is a good idea to plug in the block heater below 0.

On an Iron head engine, if you set stuck in the way cold while 
traveling, you can use a propane torch to heat the head and/or the oil  
pan (Carefully)

Way cold = below 0ºF.

Low probability might be an air leak in the fuel system that allows air in so 
the injection pump looses it's prime.  ;-)

I'd start with the preglow system as already discussed, keep this idea in mind 
if that route doesn't solve the issue.

Valves adjusted recently?

GP or relay. I just changed out a relay in my son's 123. ‎

Have you set the valves?
Proper valve clearance is essential to cold weather starting. 

>Do the plugs wear out or simply fail?‎

Yes. Short out on carbon, or open from age. You probably should've sold that 
one and kept the one you sold to Manfred's friend. Oops.

With a working block heater, I expect even my tired car to start
one dead glow plug.  I think it started with two dead glow plugs
- after the block heater was on for an hours at a temperature of
about 0 C (32 F).

Hard starting when cold is usually tight valves, failed glow
plugs, - or low compression.

Glow plugs are easy to test.  I'll post again my preferred method
using an automotive ammeter if anyone wants details.

Valve lash isn't hard, but it involves removing a bunch of the
ugly '85 stuff along with the rocker arm cover.  And fingertips
will become black from the engine oil.

A compression test requires special tools.  But if the other two
are okay, then it's probably compression.

Sounds a little like my 85 300CD, I had too stop driving it in the the
winter time because it wouldn't start even with fresh glow plugs. Turned
out to be low compression, which is needed to get the fuel to ignite. Glow
plugs draw at least 10 amps and then drops of slightly as the plug warms
up. You could also check and see if you may have a large voltage drop on
the individual glow plug wires to make sure you do not have higher than
normal resistance in each of the glow plug wires. To much of a voltage drop
means the cglow plug will not get full voltage and will not heat up fully
as needed!

Re: [MBZ] Cold starting issue - glow plugs?

[OK Don via Mercedes]

Yes, it will make it harder to start the car if one plug is bad. IIRC, the
engine will run rough for a bit until that cylinder gets warm enough to
fire. If yours is running smoothly from moment it finally starts, then I
don't think it's a single (or two) glow plug issue. Either a bad plug relay
or fuse, or low compression. YMMV.

Re: [MBZ] Cold starting issue - glow plugs?

[Larry Turner via Mercedes]

My 78 240D started easily until it got cold even if plugged in. Then it 
refused even w/new GPs.  Ended up having low compression but it gave me 
the "opportunity" to completely rebuild the engine.  I still think about 
that rebuild with pride.  Gave me 30,000miles + of trouble free driving


Have you checked the compression?

That sounds like the experience I had with my '84 300D when the relay 
failed. If the engine has decent compression it should start ok with 
one bad GP. The GPs are easy to test with an ohmmeter.

I had 1 bad plug in a 240d and it would not start at all

Quite possible too!  I've had several bad GP relays.  If the GPs test 
good, and you HAVE replaced the fuse, (and the new fuse does not blow 
the first time you try to glow) and it is still no start, then it is 
likely the relay is bad.

That sounds like the experience I had with my '84 300D when the relay 
failed. If the engine has decent compression it should start ok with 
one bad GP. The GPs are easy to test with an ohmmeter.

Re: [MBZ] Cold starting issue - glow plugs?

[Andrew Strasfogel via Mercedes]

My question was whether one bad GP would make it harder to start the car
than with 5 good ones. Two bad ones?  But your point is taken - I will test
them all once it gets a little warmer.

That sounds like the experience I had with my '84 300D when the relay failed. 
If the engine has decent compression it should start ok with one bad GP. The 
GPs are easy to test with an ohmmeter.

Subject: [MBZ] Cold starting issue - glow plugs?

On my W123 300TD, I am having a hard time getting it started when the 
temperature dips below 20 F despite the car being plugged into the block 
heater.  It takes 2 minutes of multiple glows and attempts before I can get it 
fired up. Once I get it started the engine runs as if it were preheated.

Question: Does this sound like a glow plug issue?  Do the plugs wear out or 
simply fail?  If one is dead will the other 4 start the car, albeit laboriously?

Happy 2018 to all,

As I recall you posted that you may have bad GPs several weeks ago.  Id 
you did then, you certainly do now.  Test them and find out.  it is not 
hard.  Pull the pug at the GP realy and check ohms to ground in all 5 
pins with inserts.  I'd bet you have at least 2 with infinite resistance..


Wear out or fail, your choice.  Either way they are BAD.
