W124 1-4 enjector problem

[Ramazanbekil]

Hello, my car w124 e200 1995 model. injectors 1 and 4 work for a short time, and then the energy goes. I tried a new pms, but it's the same again .please help me

You need to do a fuel pressure test first . What is this energy you speak of ? .is it fuel ?

 

[optimusprime]

I have known the EHA stop fuel flow to injectors after it gets bloked up inside with sediment from the fuel tank ....see picture for EHA You have lots of sand in your country so it just might be sand sediment,... Before you remove EHA mark its location on the fuel distributor with a black marker so you are sure its going back in the exact same place .You might need the 2 small seals to replace the old ones once you have it off to check it . Also check sediment in the in line filter it is the brass fitting on the right in the right hand picture will have a hard fuel line going in to it .

Not on that car, I think. It uses the later, integrated fuel and ignition system.

You have the lost spark ignition system where the PMS fires 1+4 and 2+3 via 2 coils. you say you have changed the PMS SO NOT THAT[ UNLESS THE REPLACEMENT IS FAULTY? --- CLASSIC SIGNS OF SOMETHING ELECTRICAL OVERHEATING--try swaping coils to see if problem shifts to eliminate a faulty coil--- 95 was a bad year for engine wiring so that's a possibility ALSO---- the PMS GETS ITS TRIGGER FROM THE CRANK POSITION SENSOR SO POSSIBLY THAT-- BUT THAT WOULD LEAD TO COMPLETE IGNITION FAILURE.

Ray whats this then .

Thats a CIS [continuous injection system] from a 200E with the m102 2 litre engine single cam [ with distributor] NOT the later E200 M111 twin cam 2 litre PMS sequential injection system engine with twin coil ecu controlled ignition -- engine change occured around 1994

fuel comes 1 minute after the first start 1 and 4 Pistons do not work. injector power goes out

thank you, man, but I did a test that doesn't stop firing injectors don't spray gasoline

SOUNDS VERY LIKE YOUR REPLACEMENT PMS IS FAULTY! IT MAY WORK OK FOR A SHORT PERIOD TILL SOME INTERNAL COMPONENT OVERHEATS- THEY ARE SEALED UNITS AND NOT EASILY REPAIRED DO A FORUM SEARCH FOR MORE INFO.
E.G.

W124 E200 with no ignition on cylinders 1 and 4 | Electronics and Audio

Need info on PMS ignition control unit MB#0185451032 bosch#0261200608. Car (W124 E200 with M111.940 engine) has dropped ignition on cylinders 1 and 4 and the coil is OK...swapped it over with the coil for 2 and 3 but fault remains with 1 and 4. Any advice, repair options or pictures of...

thanks mate .but without heating, the injectors fail.I've tried the pms unit in another car, and everything looks good in that car.can there be an error caused by x11b socket connections?

 

[grober]

you are unfortunately in the period of dodgy wiring insulation- it goes brittle and cracks causing electrical shorts any movement/bending/ stretching during maintenance can cause problems.

the cables are new .do you think X11 b socket connections can be an error source?

Do you mean the engine harness has been replaced or the HT leads?

Try swapping the coils around and see if the fault moves to cyls 2/3.

if I look at the diagram, it seems unrelated to the X11 socket, just a possibility . I changed the coils, but the problem is again in 1 and 4

What's the part # of the replacement PMS?

original end 7032 .but I tried the end with 7232 unfortunately the result is the same in both

I believe 015 545 72 32 is for a W202 C180. 015 545 70 32 is the correct unit, assuming it's an automatic.
