Thank you! I am troubleshooting my 1988 560SL. This is very useful information

[@paulbaker6233]

Great info.. as I am waiting for a replacement relay.. Thanks very much!

[@zenjamin6262]

Love the honesty.. a tow truck is 200 on average.. I'll go with the best relay possible.

[@renatopignataro226]

[@mahmoudshojai431]

[@classicjalopy]

Good info!

[@Vaudotusker]

In Australia a genuine MB relay is over $900 and a 3 month wait ! I went with Beckman and never looked back. My 190E works very well however my Klima relay is starting to quit. We use A/C all year round here so now I’m searching for a decent air cond relay

[@vmlelectronics]

I've overhauled mine, ressoldering the components and the terminals. And more, I've added an emergency relay inside it that shorts the proper pins once the extra wire gets grounded.

[@tomzouzoulas3169]

Great content as usual Pierre. Detailed and informative!

[@xmaxbabilo]

refreshing to hear straight forward approach. keep it up.

[@inovahightechltd]

Pierre, the advice I am most grateful for you have given, was the 1 - 3 mm play for the plate adjustment to get flow plate to the correct position to start - this allowed me today to start my car at 0F with the initial adjustment being made in my shop at 65 F

[@jessevongnaraj2276]

I remember driving my 230e in Kissimmee and my fuel pump relay had died One little jumper wire later And i was driving around like nothing had changed I made it back to the space coast after no more hiccups Check your fuel pump relay!

[@walterdavis4007]

Love the channel Pierre, I just wish I could see more w202 vids.

[@airenesivad2975]

Came from coffeezilla I did landmark too and love classic Mercedes. I had a 300D

[@jeffcarruthers2605]

Thanks Pierre. I wasn't aware these relays were hard to find and the after market versions were basically junk.

[@fernandomangino9773]

Hi, excellent information! I have the mystery stalling situation you described and its finally solved... ! It would be great if you posted a close up picture of the original OEM Mercedes and Strider acceptable substitute relay to better identify them. Thanks!

[@ShinyRedGrapple]

I have a stalling issue, Im going to try by passing the relay THANKS

[@69oakfan]

Thanks for the video awesome as always, I have a 1987 420sel, and a 1991 560 SEL (parts car).... will the fuel pump relay from my 560sel fit into my 420sel? Thank you

[@bobbuilder5362]

Just bought a New KAE, one for a 280se. Now I'm thinking I should get another new genuine, or rebuilt one just in case.

[@user-if4ly7ez9w]

I always carry one with me inside my m103 300ce. I think what makes the go bad is moisture, the casing is not water tight

[@vintage76vipergreenBeetle]

👍

[@rhabdo6630]

Thanks Pierre! I have a 1993 Mercedes 190E 2.6L and was pulling my hair looking for the fuel pump relay as I don't have one located adjacent to my over-protection relay. I only see a MAS relay and as you stated 1993's don't have them. My 190e has been sitting for about 1 1/2 years and now it's having a hard time starting up. Usually takes 2-3 cranks of the ignition key then starts up. It stutters, shakes and wants to die and needs assistance by pressing on the accelerator. I'm about to change the fuel pumps, fuel accumulator, fuel filter, fuel injectors, bottom fuel tank filter screen, threaded fuel distributor filter, and fuel pressure regulator as they have never been changed since the factory. Any additional advice, please reply. Thanks!

[@Johnathan_Waters]

The reason these cheaper relays fail (in my experience) is due to moisture ingress. The cases aren't weatherproofed AT ALL!

[@jungletension2835]

Oh no I bought a KAE railay. For my 300D up near the driver side hoodspring

[@Uc9uE3pKsS6uQ]

If you have that kind Merc, the firs thing you need to know how to, Is jumping the pins with 6 inch long wire to make fuel pump running no meter what.

[@igel1]

Some old Volvos whit KE-jetronic have the same problem whit there fuel pump relays.

[@cardiffchris]

Time to buy a vintage Benz

[@stevesutton9444]

Hi Pierre, I did leave a comment on a previous video, I can't remember which one, where I asked the question about my car. On a reasonably long run, the car drives faultlessly but coming to a stop, the engine dies, not always, sometimes, it restarts no problem. I have replaced the relay, VCB, alternator, potentiometer and fuel accumulator. I would dearly like to cure this problem as it really is quite dangerous. Any ideas? Its a 91 W 124 E300

I always have a cable-bridge in my glove box for pin 15 to 87 in case the relais fails.

[@MrStroller4u]

and that is why i bought a diesel.

[@ItsTimePictures]

As soon as the video started I began to wonder, "Is that the relay I left at your shop?" Thought answered. :-) It figures that it was going to be something simple. So for those reading comments, I always keep a spare relay. I have a rebuilt relay from the company Pierre mentioned, which replaced the relay Pierre was holding in this video, which had replaced whatever relay was in my SEC when I purchased it. HAVE A SPARE! Even if it is crap one from eBay as long as you have tested and know it works it's good to just have one in the car in case of afailure.
