Mercedes W123 - more fuel system shenanigans

Special thanks to Chris Shergold who sent some incredibly useful manuals over to show what we needed to do.
So the non starting Mercedes 230E W123 was bothering regular viewer 'The Fake Russian' - an ex mechanic who thought he'd spotted why the old Merc wouldn't fire, so he came down to see if we could get it going.

Matt, I've been looking forward to another W123 video. A shame it isn't running. It is worth having a go at cleaning the accumulator. Carb cleaner is a bit better than brake cleaner. You're so close to getting it running and all the grief will be worth it in the end. The W123 is the best car Mercedes made. Don't give up on it. I'm sure you could pick Kent's brains somehow.

[@Chipchase780]

Reminds me of many hours spent stripping and reassembling the twin carbs on my 1960 Singer Gazelle with new gaskets, supplemented with red liquid gasket. I used it liberally, but petrol still leaked. A filthy thankless job. I don’t have the time, patience, or stamina anymore. I like my 21st century Skoda Octavia which starts first time and never breaks down. Happy days.

[@midlifecrisis.2409]

Almost forgot to mention, i had an 87 Audi !00 with Jetronic. On cold days it would lose all power after coasting,followed by a monster wheelspin as the power came back suddenly! Turned out it had an overrun cutoff valve which was sticky and was taking it's time to close.This valve worked by breaking manifold vacuum to the sensor plate while the car was coasting and foot off the gas, basically all fuelling cut off in this condition. I don't know if your Merc has this but if it does it might be worth a look.

[@grayfool]

I know this isn't much help but from what little experience I've had with the fuel injection systems on the W123 series, every part has to be in good operating condition for the thing to work. My 280E was a bit finicky until I replaced all the injectors and fitted a good used metering unit. Then it worked pretty well. If you haven't already, check out Kent Bergsma over at mercedessource channel. He is a mine of info on anything that is old Merc. Good luck with it. I'm sure It'll be worth it in the end .

[@TheFakeRussian]

Thanks for a lovely day, sorry we couldn't get it started but we tried! And sorry for the swearing, (bleeped out), as I did promise to behave myself hahaha.

[@TheFakeRussian]

@Lime Pringles True and thanks for the kind words *BUT* I should have made the phone calls and done my research first. I'm now convinced it's the fuel actuator/valve/regulator that's not opening and closing to deliver the fuel pressure to the injectors, (though they may need a good clean out now given the gunk in No1 injector and its feed pipe), which is why it's a non-starter. I reckon 2 days and a complete overhaul of the fuel system, (filer, pump and pipes cleaned), and this car may just start. It's pure fuel starvation stopping it starting.

[@thomas316]

These K-Jets are very sensitive to fuel pressure. As I recall that pressure is set and maintained by a regulator in the return line (and can be adjusted.) Someone said something in an earlier video about relays and I think the reason for that was the fuel pumps in these often deliver low pressure due to an electrical issue but I can't recall what that fault is. Either way easy to ascertain if its the pump by checking fuel pressure which needs to be over 3 bar to actuate the injector system. You did a great job! 🙂

[@TheFakeRussian]

@@thomas316 I really don't think it's the fuel pump as it's new. You're right about them being pressure sensitive though and I honestly think the gate isn't closing on the regulator to give it enough fuel pressure to deliver fuel to the cylinders. I did take a pressure tester with me but we never used it

[@rimmersbryggeri]

I would think it's the timing of the fuel pump that is off. Pretty common on this type of system after they have been apart, especially if there was some issue with the drive belt for the diesel pump.

[@TheFakeRussian]

@@rimmersbryggeri Ermm no, it's an electric pump that fires up as soon as they key is turned and the regulation of the fuel, (fuel pressure and delivery), it because of the accumulator/actuator opening and closing to divert fuel to the tank on the return or divert it to the injectors under pressure.

[@grahamclark4518]

You WILL Crack it. Hang in there

[@drazenradosevic7467]

I made a similar mistake once, buying used Audi 80 (2.0 16V) with K (or KE, don't remember exactly) Jetronic. It was running, but it was incredibly thirsty and sluggish, and also had a tendency to stall when cold (usually in the middle of a busy crossroads). Nobody was able to fix it, so I got rid of that car ASAP and never looked back.

[@p24hrsmith]

I had a Skoda 110R Coupe and on the way home it cut out and refused to start over the next 2 days I went through everything. Totally stripped carb apart 3 times cleaned it, replaced all ignition bits even though had a good spark, checked timing, check compression and even adjusted the tappets in desperation. Day 3 I'm at my wits end with no idea's left other than to lay into it with a sledge hammer and set fire to it. So it was the afternoon before I decided to take yet another look and without doing anything turned the key and it fired up straight away and run perfectly. What the hell the problem was I had no idea so I sold it.

[@eurohouse8788]

Awesome. I have a few W123s I am currently restoring

[@tydale8629]

Maybe there is air in the fuel lines before the fuel injectors? I know with the 300sd if you take the fuel lines off that connects to the fuel injectors that you have to prime the fuel lines and crank it a couples times with the fuel lines before the injectors cracked open until they squirt fuel, indicating that you have gotten all the air out of the fuel line and then you tighten them up on to the fuel injector.

[@jacobbelcher3512]

When working on a w123 or w126 it helps so much to open the hood all the way. It would make it so much easier if y'all opened the hood the rest of the way. There are little tabs on the hinges that need to be released. Lower the hood some and push the tab on the driver's side and raise the hood as much as possible. Then push the tab on the passenger side without lowering the hood. Then the hood can be raised all the way to the vertical service position. Edit: Whoops. I'm American and the driver's side is on the opposite side. The first tab is on the left side of the car. Release them from left to right.

[@furiousdriving]

This is up as far as it wasnt to go, Ive pushed it into service but it wont go vertical and Im not going to force it!

[@AliMackMechanical]

I have never worked on one so couldn't give you any advice. Looking forward to next video. I hope your successful with it buddy. 👌👍👍

[@gosportjamie]

Well, it may not have delivered any form of definite, positive conclusion, but the exercise has given you new directions to go in, even if they are expensive ones. I would suggest filling the accumulator with something like carb cleaner and leaving it to sit overnight as that ;may, hopefully, dissolve the varnished fuel and inevitable rusty sludge that has accumulated in it over the last 35 years. I have seen people use things like cellulose thinners or panel wipe on heavily varnished fuel system parts so that could be another option, and probably a cheaper one...

[@sun-p6g]

Likeable non affected presentation. A completely different approach to me though. I used to get the haynes manual and the factory one if I could then strip down and check the lot, renew the rubbers, rebuild the carbs, take the head off redo the valves, shim parts of it and so on then I know it is going to drive.

[@TheMentalblockrock]

The simple solution is just buy a GIANT can of easy start and run the car on that!

[@arnonmus1]

Is it a good idea to smoke whilst working on a high pressure fuel injection system? I had a 280se which also turned into an aquarium every time it rained. Eventually I could see the road through the floor pan. Good luck with the gremlins.

[@FirstOnRaceDayCapri2904]

K-Jetronic does not tolerate at all somebody who doesn't know what they're doing messing around with it. If you have fuel getting everywhere else but not the injectors, that could mean that there is fuel pressure, but it's too low, the injectors have a set opening pressure and will not open if there is not enough pressure in the system. The warmup regulator is what controls this, it has a bimetallic heating element inside, and a plug through which it recieves electricity, which varies the fuel pressure ( known as control pressure ) , there are small shims inside that are either removed or addded to vary this fuel pressure although it does come pre-set from the factory. The accumulator has two functions, one is maintaining the fuel pressure for 20 minutes after the engine has been shut down to prevent vapour-lock, and another is to smooth out the pulses from the fuel pump to create a smooth constant pressure and flow to the metering unit. With that being said though that metering unit sure looks like it's been messed with far to many times and is probably knackered, but do check the warmup regulator and verify the control pressures both cold and hot, ( you will need a fuel pressure gauge ) and looking up on the internet what is the correct cold and hot control pressure for the particular model. And, whenever the metering unit is taken apart, new seals and gaskets should be fitted. Contact KMI Petrol Injection Engineers LTD, they are real genuine experts on K-Jetronic!

[@furiousdriving]

The warm up regulator is also suspect, Ill be looking at that and the regulator before I drop £500 on a used metering unit!

[@furiousdriving]

I had a quote from them to rebuild the distributor, they look helpful

[@jackjacko8706]

Fuel Accumulator is only to hold pressure in the lines when the engine is hot. To avoid vaporisation in the system. To make starting easier on a hot engine. It consists of a diaphragm with a spring in the low pressure side which the fuel pump compresses. When the engine is stopped. The spring presses the diaphragm back , keeping pressure in the lines. Eventually pressure is depleted . The cold start valve takes over on a cold engine. So I do not think it is your problem. Mine has not worked for a while, but car starts up first thing when cold. I turn the key on and off a few times when hot, this pumps the fuel back up, before I hit the starter. To test. Attach a bike pump to inlet and pump up whilst holding it under water. If bubbles come out of the outlet, it is R/S. I presume the small brass mesh filter on the inlet of the fuel distributor is not gummed up? It is the size of a match head.

[@Joloke08]

Your too close now Matt to give up! The Accumulator maintains pressure so when you walk away from you car it will have the pressure to just fire up again ;) I was going to suggest a great place I bought used spares for for years in Gloucester but sadly it looks like they have now gone :( Try the accumulator then if that doesnt work try and track down the whole kit carboodle bosche system from a running car. You Wife might not be too pleased but have you thought of a good running basket case as a spares car? Might be cheaper in the long run? Jo

[@TheFakeRussian]

Ahhh now what I've found is that the fuel accumulator/actuator/valve prevents the flow of fuel back to the tank to pressure the injectors then when the car fires it opens so excess fuel pumped up is returned to the tank. Once the car starts the engine maintains the pressure mechanically because there's no ECU involved. I've also found I was partly right in the respect that after the exhaust stroke, the vacuum of the down stroke draws the fuel into the cylinder maintaining the right amount of pressure so the engine won't over run.

[@thomas316]

What's the fuel pressure like? It takes a lot of pressure to actuate the injectors (45psi) so if the pressure is low you won't be able to push fuel through the injectors.

[@lodewijkvan96]

A w126 V8 with a K-jetronic needs 75psi, if not or not close enough like 50psi the distributer sinds it's just right back to the fuel tank. Also happens on the KE-jetronic

[@TheFakeRussian]

@@lodewijkvan96 You sure about that? I got a little pamphlet with my fuel pressure checker and it said Merc was 29 to 30 psi .......... But then that could be for cars with an ECU controlling the fuel pressure and injectors. This one might need more because it's purely mechanical fuel injection.

[@lodewijkvan96]

[@TheFakeRussian]

@@lodewijkvan96 My understanding is the fuel pressure accumulator gate closes to divert fuel and fuel pressure up to the distributor and down to the injectors and when it's at level the gate opens allowing unused fuel to return to the tank with the engine creating it's own vacuum and pressure to maintain the engine running. Now I could be wrong and shall await your looking at your notes :)

@@TheFakeRussian I looked in my notes and rememberd it all wrong haha. You're right when the pressure is all good than the left over fuel is send back to the accumulator.

@@furiousdriving my question was not to ridicule but from an abundance of concern. keep up the great videos.

[@TheFakeRussian]

In an enclosed space where the fumes can build up it's not a good idea. But outside and a cigar/cigarette smouldering at around 400c won't, (and didn't), cause ignition. It matters how the cigarette actually falls onto the surface to the petrol. There is a lower chance of autoignition if the cigarette falls on it's side where the temperature is lower. Naked flames are the true enemy which is why there's no smoking in combustible areas because all cigarettes and cigars start with an open naked flame. Anyway, I had a fire extinguisher in my car and told/showed Matt where it was so he could chase me around trying to put me out.

That is a great idea and the 2 litre version of same engine had a 1.75" Stromberg. Find the manifold for that and put an SU carb on it. Get one from an automatic car, that has the linkage for the kickdown cable. Might reduce top end power a little, but would provide great economy comparable with injection of that era, but far more reliable. Will also require ditching the high pressure injection fuel pump, for a low pressure type.
