Engine will not start or has no power W126 W124 R107 R129 SD 480p

That reminds me that back in the days of carburetors in the 60s and 70s, carburetors had a little filter in the line where it entered the carb. It looked like a very porous little stone. Most people I ran into did not know it was there so never cleaned or replaced it. It was the cause of a lot of fuel delivery problems. Thanks for the video Ralph.

[@straybenzes]

It is the simple stuff that often gets overlooked.

[@libran58]

Yeah great, I did it and found some small bits of metal, after cleaning it definitely started better. Now I've got to put on a new fuel filter. Thank you for this info!

[@straybenzes]

Glad it helped.

i have w124 230E, was driving it on the freeway, and the engine just went and tried starting but its not responding, ill try this hopefully will start.

Good luck!

[@ace7821]

Will this bog the car down? Mine is from a rebuilt fuel distributor and the car big down at 60 mph. Why?

[@straybenzes]

That can indeed cause such an issue.

[@hamshank29]

Could this be related to the issue im having - car starts and then dies immediately. Occasioanly will run for a 2 mins and then die - pressing the accelerator kills the engine immediately. The fuel pump is new and the filter is only a year old. I have tried jumping the fuel relay and the pump but it made no difference.

[@straybenzes]

I will need to make a few assumptions. Assuming that you have good supply fuel pressure to the fuel distributor than a plugged fuel pre filter at the distributor can cause a no start issue. It is easy to check that. This condition could also be related to the EHA being out of adjustment. Finally, it can also be that your start up / warm up fuel injector or it's valve are not working correctly.

[@hamshank29]

@@straybenzes I checked this filter and it was clean plus there is fuel reaching the distributor. I will check if the air metering plate has the correct gap but it seems strange that this would suddenly be off.

[@straybenzes]

@@hamshank29 Yes, that is highly unlikely.

[@hamshank29]

@@straybenzes is there anything else I can check that would cause ovefueling? Some people on forums are suggesting the EZL could have gone bad but im not sure how to test it.

[@straybenzes]

@@hamshank29 One test you could do is to take off the main supply cable from EZL to distributor cap and position the cable end close to bare metal 1/8". Don't hold that cable as you may get a severe electrical shock. Have someone start the car and see if you get a spark. If there is a spark the EZL is most likely ok. I say most likely, as these tend to fail under load and also tend to malfunction as they warm up. If there is no spark then the EXL is most likely defective. Be careful!

[@hobbyavenue6740]

Thanks for the video. I currently have a 1990 190e 2.6 no start issue. I will order this new inline filter and give it a try. Do you think a aftermarket filter will be fine? Seems like a few weeks or months wait for a genuine part.

[@straybenzes]

The aftermarket parts can work - if it is a nice car that you want to preserve and show go with the OEM part. This filter - assuming it was clogged - goes often unchecked and will cause a crank but no start issue. However, a busted fuel pump, fuel pump relay, fuel pressure set too low, etc can also cause the same symptom. I hope this will help fix your car.

[@shaazy]

Did this work? My car is a m103 and I was driving it pretty much every other day. Sometimes it would do slightly long cranks to start, sometimes it would start at half crank. Today it sat for 3 days, and wouldn't start up. It would crank endlessly but won't turn over.

[@tefangpao6554]

Can you tell where can I buy this inline filter? If possible, could you please send me a link? Thanks!

[@vicwahbyphotography4866]

Hi Ralph - That's a great tip! I wish we could see the screen in that unit, and understand how to blow it out and from which end. Oh, also, separately: Do you either have a video on tire recommendations or any specific tires you've had good experience with? My Continental Super Contact tires sat too long and they were always a hard ride, even now that my shocks are replaced. Thanks and best wishes. Vic

[@straybenzes]

The filter comes off the fuel distributor really easy and you just blow it out with compressed air from the back side. You can see if it is / was blocked up with foreign objects. As far as all season tires for the std rims are concerned I have had good luck with pretty much all name brand tires ranging from low cost General to Conti, Goodyear, etc. It really comes done to personal experience and preference. You may find Tirerack.com's tire selection and recommendation site useful for gathering some feedback about your next choice of tire. Good luck.

@@vicwahbyphotography4866 These fittings are sealed using so called crush rings made from aluminium or copper. I would not put anything on the threads as you run the risk of that stuff also getting into the fuel system.

Nice video, never knew it existed... I went to my car and looked for it, it’s a M102 engine. 2.0..I found it but there was no mesh...it was open ..is this normal?... My car won’t start.....I have replaced, pump, filter, plugs, cap rotor...just cranks.. Thank you

[@straybenzes]

As far as I know there should have been a pre filter. Is this a W124 200E? Next thing to try is loosening the fuel injection line on top of the fuel distributor block one by one while the ignition is on and you are pushing down on the air mass flow flap. If it does not you may need to jumper the fuel pump relay so that the pump will definitely run while you are doing this. If fuel does not flow it may be the fuel pump relay, the fuel distributor, and / or the air mass flow flap adjustment is off.

[@bradowen9418]

My 1990 300e also did not have any mesh - I am wondering if a previous mechanic replaced it with the wrong part...

[@halkawtkarimi9780]

I have same problem with mine I did think about this filter I did cleaned it up still not joy what's next move

[@straybenzes]

I would jumper the fuel pump relay and crack open a fuel injector line to see if you have fuel going there at all. Then I would measure the fuel pressure to see if you have sufficient supply pressure. That should be a good start.

[@dustblowboro]

Is the filter needed in that place? I mean, will it run without (pressure?)

[@straybenzes]

It will run, but would you want the junk in your injection system if you left it out?

Hi guys,I bought 300se it starts well but has absolutely no power hence on a hill hence it does go up the hill reversing. What could be a problem mind you I have changed plugs,fuel filter,air filter and oil filter. Please assist.

I would check the fuel pressure of the EHA. That is the likely culprit of this issue assuming you have a KE Jetronic.
