Dude thanks so much for this video, I've been chasing this issue for awhile and hopefully it's the fix
It could also be that the relay, since it's mechanical, gets old and the connection no longer have the correct surface.
It is also a bit easier to disconnect the relay and measure instead of in the ecu.
If there is 12v to the relay it's most likely the relay.
Thank so much for your videos Keith!
If want to check the relay fast use a air compressor and blow cold air on it and it wil start in seconds . Also works on crank and position sensors .
I have the same problem in my gas 2011 ML350 when hot, specially during summer hot sun at noon, the car does not crank at all and no dashboard lights just like the battery is completely dead. Please tell me how that can be fixed?!
Highly impressed. I don’t own a Mercedes but have been considering it. Your explanation of this issue was great.
Faulty Crank Angle Sensor will also give you similar symptoms. Cheap part, but a bit of contortion may be required to replace it on certain models. Typically, the car while die when coming to a full stop (e.g. Stop light) after it gets hot. Then the car may not start for a while after that. However, after a few minutes, the car starts up again.
yup.that was happined to mine good point!
Simply to check if you measure a rev
would spraying the relay with CRC Freeze-Off Super Penetrant be a good test
Very interesting on your work
This just happen to me. Me and my son was coming home and just a block from my home, it died. Wouldn't restart, so we towed it home with the help of a friend. The next day it started fine. It had been not driven for serval months since it was used by my EX - my sons mother. I felt it needed a tone up because it ran rough at times, shaking at idle and it seemed to have miss firing going on. I replaced the plugs, tested it and made a block. It still was running a little rough but better. Like you said in the video. I let it run in my driveway for about 30 minutes and it died while me and my 9 year son were just sitting inside talking and it wouldn't restart either. Thanks for this video Sir. At least I have more clues to address the issue. I was also considering the crack sensor but I will start here first. Again awesome video - Thanks
Did this solve your problem please I have the same issue on my ml350 2010
W210 230E same problem crank but not start when its hot. After its cold start normally
A faulty park neutral switch was problem in our 2017 Mercedes Sprinter (2018 Pleasure Way). It was never diagnosed correctly by Mercedes dealers until I found the dealership in Rocklin California. They fixed it under warranty and we have never had this problem again.
Ah yes... that will do it also.
so many videos, so little time. Your videos are helpful and I'm learning a lot. Gives me confidence when I speak to professionals. I have a 2009 gl550. Yesterday, it seemed to have an electric malfunction. AC, going off/on, battery(red) & other fleshing on the dash. Periphery lights going haywire. Then after about 5 minutes, just as suddenly as it started, it stopped and everything functioning normally. Until this morning, dash and interior lights but no ignition. Any suggestions?
Salute Keith. I remember I had this issue on my 1998 E320. This was my crank shaft sensor. This was a real pain. Stay safe. Thx for the content.
Ha...metoo! SLK 350 171 2005. Engine warning light on and slow to start when hot. iCarSoft diagnosed crank angle sensor fault. After reset, all worked - for a couple of miles, then not. Local repair shop replaced sensor. End of drama.
@@1945sas that's when a specialist can fix it under 20mn because he knows the failures with these cars
@@glasser2819 yeah...I live 2 hours from one. Local guys had no problem figuring it out.
Someone had this issue on w164 , OM642 engine?
I have the problem that it takes a lot of time to start when the car its hot/warm near to 90 Celcius... we have changed all the sensors of the engine. fuel pressure is ok and no check engine light, also no error on the scanner.. any help please? its a ml350 w164
Thank you for all details .. good luck
I have the same issue, thank you.
Bro im in france i have the same problem the morning its startin very well but when hot she wont start it is a mercedes gl class 350 can you help me
would spraying the relay with CRC Freeze-Off Super Penetrant be a good test
1986 MB300E W124 Cold start no problem, hot start hesitates and often takes time until cooling off. Few times after driving several miles engine went off at a stoplight. Pulled to the side waited 15 minutes and then cranked and engine started. $3k spent on repairs, changing, relays, fuel filter & pump, etc. Last mechanic told me to find another EZL. Is the EZL on my 1986 MB 300E repairable please?
Hey brobro, mines turn when it wants. Weak start after many tries. What could it be if i have new battery and starter. Thanks
Relay in the foot well below glove compartment for starter kontaktor is high resistance

I think this is the cause of the intermittent starting on my Mercedes SLK 350 2012. Only happens when it’s hot. I will tell the dealer this when I take it to them tomorrow
ok my 2000ML430 nay have 2 issues. I have random NO start but turns over, I thought it may of been ignition immoblisier transponder, Orderd it waiting. But, randomly key sticks in the ignition, That may be the tumblers. And When the truck has been running it stalled today with turn over no start. SO wondering if I have fuel snensor or pump issues too. Dang it! lol letting it cool at aprking lotup the road, gonna check it in an hour see if it starts cold.
Hey, nice video. I got the same problem. However on mine, the starter won’t even try, I just hear a click when I turn the key and that’s it. It also has to do with the water temperature I guess. If I open the hood and put cold water on the starter area, it will start faster. Weird stuff.
I hear click to relay but sometime fuel pump not on can I borrow or tap ground from other relay to make work?
Thank you for your advice God bless
Hello, my vehicle is Mercedes w203 2001 model M111 compressor . Hot engine does not start at 1st start 15 minutes after it stops, it works at second start. What could be the problem? What should I do? Thanks?
I have the same problem how do I know weather it is the ladder or ECU that have the prodlem
Great job ❤❤❤
I know this is an old video. If I have this issue in an old van can I wire a bypass between the pins
Finally!!!! Thank you!!!!!
Is this applicable for diesel engine like toyota commuter?
Thanks Keith.
Im having a similar issue on my 2007 c280 it will start fine over & over then i drive to store, 15min or more later go to start it & sometimes it wont start, then i wait 5 mins & it will usually start, do you think its the same issue?
My 02 clk 430 was doing the same and then would shut off when it hit normal running temp...
Do you have video for power steering pump 2011 Land Rover sport hse? Thanks
And, thanks Keith!
Hey my man watch your videos all the time super helpful do you have no idea how much money you save me can’t thank you enough I was wondering if you could possibly shed some light on the current situation I’m having with my ML 500 W 163 body style I thought I had a starter issue because the truck would start. I had to get one click and that was it, so I replace the starter and I replace the battery. Then I replaced the relays and all the fuses tested them all all working or at least getting power to Changed the brake light sensor safety switch as well as the crankshaft position sensor. I just don’t know what else could be left. I start the car get one click and that’s it if I put direct power to the starter same thing one click and that’s it almost seems as if the fly wheel is possibly jammed or stuck. I took a look at it the best I could, and none of the teeth are missing or, even damaged for that matter from what I can see I’m seriously at a loss and just don’t understand what else could possibly be left. Thanks again for all the help of videos and hopefully he’ll respond to this at your convenience. Thanks again so much appreciate everything you do.
Mercedes cls 2009. When its cold starts after 2-3 seconds. When engine is warm, starts only from a second time and after 6-7 seconds. Is it a same problem?
Bro. Keith: it's better to start from the pump relay with a swap (plenty to choose from on rear SAM!) than back probing the ECU Pins.
The front radiator fan RELAY is also a good candidate to keep healthy on high mileage vehicles
👍
As Lars mentioned Nino. Engine is not really that hot !!! But the Relay could be. Stopping the ECU sending 12v to the pump relay.
Good info Keith😄
Hi mercedes c230 2006 starts you can hear pump, after a while shuts off and dies, after a while could be 1 hour or more if not hot outside otherwise till next day and pump works for a few minutes and shuts off

Hey good evening! I have a question? So I have a 2010 AMG E63, when I rev it on park it turns off sometimes! What can it be?

hello friend i have the problem of my 270ml cdi 2004 cranking about 2 seconds and it stops without starting 5 to 7 times without starting i have changed the starter motor and changed the ignition antenna i have checked all the fuse boxes i have found All are going well I have changed the battery and without news but when I connect it with cables with another car working it starts directly. now I do not have to think about any reley that is main! do you know if he has any ??? please help ...
I have my r350 07 at my brothers I swapped the board in the new used trans it ran on way in but only started and ran 10 minutes then died where is the pins
Is it the same if the engine is to cold?
I have the same problem when I turn the car gets hot won’t start right away anyways… does anybody know where the fuel pump relay is on an ml350 2012 w166?
Nice 👌
I had just this problem on my 2011 MB E350 Blutec that I just bought. I was going to go through the checking and thought I should have a new relay in case it was the cause. I got in to the trunk fuse panel and, lo and behold, there is no relay at all. There is a fuel pump fuse and I didn't look at any of the other boxes for missing fuses, but this one stumps me. Would there be a reason that there wouldn't be a relay? I checked four different diagrams and they all have the same placement for the diesel relay and there is no relay in the slot. How could this car be running? I'd love for it to be so simple as just pop in a relay and my car won't leave me sitting at a gas pump for half an hour again, but I'm afraid it's like that for a reason I don't know and I might wreck something if I put in a relay. Anybody know why there might not be a fuel pump relay in my starting and running MB diesel?
I changed my v-belt. There the car won't start making a click click click sound more from the computer box.
I need to tell that my engine's temperature was not hot either - just normal.
I have a mercedes ml280 2009 model w164 deisel cranks but wont start iv changed glow plugs crank shaft sensor and glow plug module also changed fuel filter and sensor and still nothing only way to get it to start is to spray in air intake then it starts but as soon as I stop cranks but wont start
try ignition immobilser transponder. The ring could be bad.
