As a sequel to our previous event regarding K-Jetronic fuel injection, MBCA and Pierre Hedary discuss KE-Jetronic fuel injection as it pertains to Mercedes-Benz vehicles. Also known as CIS-E (Continuous Injection System - Electronic), KE-Jectronic is a combination of mechanical and electronic injection systems. While similar to K-Jetronic, there are some critical differences. Included in the presentation will be an overview of how KE-Jetronic works, diagnosis of common issues, and recommended repairs and adjustments.
Overview of the system and its components
Differences between K-Jetronic & KE-Jetronic
Troubleshooting guide and common stumbling blocks
Adjusting KE-Jetronic
Considerations- reliability, pluses and minuses

what would cause fuel coming out from all top port with plunger all the way down (idle condition) after fd rebuild? haven't troubleshot much but as soon as pump is shorted to run manually, fuel comes out n loud buzzing/whine happening, like fuel pressure oscillating... i'm thinking either EHA adjustment is wrong or fuel pressures are wrong...

Hi, I have a W126. 1990 560 SEL. All of a sudden, I have a rough idle and lack of power. The low rpm idle stalls the car if I don't depress the accelerator. I replaced the fuel system, new ignition distributor, rotor, spark plugs. I am trying to troubleshoot the Idle Control Valve. At this point, I am seeing continuous fluctuating voltage (0 - 2.1V) at the terminals of the ICV when the car is cold. Could this sysmptom be a faulty Idle Speed Control Module? Or something else?

Pls I have my w124 using k jetro bt my car is mixing petrol and engine oil I have been looking for help never found any it is misfiring blue smoke wet spark plugs the mech once adjusted the sensor plate bt the problem came back after a month help me he says it's a bterfly problem help me

My name is MoeRalee. I have a 1990 Mercedes Benz 300 SL convertible roadster with 2 fuel pumps. How can I find out which fuel pump is bad. My car idles rough with no acceleration

My 500ge misfire's when its hot, what could cause this problem? I replaced the spark plugs and wire's Ignition coil Rotor and cap When i replaced the rotor cap and coil it was running perfect. A week later it was misfiring again and the engine shakes.

Excellent presentation Pierre! I have an '86 560SL to diagnose and the info in the video was helpful. The engine starts immediately and then shuts down within 3-5 seconds. Starts right back up and then dies again, over and over.

Hi. Very helpful information. What do you think about the electronic fuel injection upgrade kits? Are they better than the original mechanical system?

@henrysalem5516 7 месяцев назад

Thank you for all your effort. I have 1986 190e 2.3 8valves, gas, and please correct me on the following steps on calibrating the EHA valve: 1- Engine at normal temperature 80 degree, 2- install pressure tester lines, tester valve closed, unplug EHA, 3- start the engine 4- take the reading 5- open the tester's valve, 6- taking the reading, 7- after I reach 0.4 bar difference, turn engine off, 8- discounted the tester lines, 9- plug in the EHA valve's electrical. Thank you

Well... you should NOT adjust the mixture screw, to get a better idle.. you should NEVER adjust it, period. Just leave it alone. And it's not for idle adjustment, what the hell? BTW, we do not want 1-3 mm's of free play in the plate - we wan't 1,9 mm.

@stevedeardorff 3 года назад

minute 40 why would a blocked injector cause the engine to run rich?

@alistairtassie1614 3 года назад

I think the O sensor would read lean, thus richening the mixture overall, causing the others cylinders to run rich, plus the rest carrying the load of a not correctly functioning cylinder will make it use more fuel. Same thing happens with a blocked jet in a carb, fuel economy plummets!

Hello Engineer, do not be tired, God help me, I have a motor wiring diagram m102982 I need it very much

@gogglespaesano2931 3 года назад

At 26:26 should it be turned clockwise or counter-clockwise?

@xg9011 3 года назад

Clockwise to increase the pressure difference

@philippbehrenz9669 3 года назад

Great Video👍🏽 i have a question My se300 from 88 doesnt want to start anymore after i replaced my fuel Pump, because the old one break after welding. The new one is from Bosch old one not. There is fuel in the cylinder and sparks are Ok. Engine was running before welding. Thanks

@marianflimel318 2 года назад

I have 4 Mercedes at home, 3 of them Are non runners, this guy is an absolute beast in old mb! Thanks so much, looking forward to start working on them

@terran5569 Год назад

Where can we get a fuel pressure kit exactly like yours?

@shanedoyle1057 Год назад

Loving this channel. Wish I knew about it with my old 114 D-Jet Does anyone here know what the issue is with a 124 300CE which won’t creep forward by just releasing the brake? In other words I need the throttle for car park or parking manoeuvring. Any help would be much appreciated
