Dave, Ok will do what you suggest tommorrow. When i said it was fluttering, you did realize It was doing it with the engine not running. And for sh@# and giggles I'll also reverse the ICV to see if maybe it was put in upside down. And I'll also try what you suggested too smk texas. Trust me I'm not laughing at any idea at this point. Kinda getting tired of picking my tools from the neighbors yard from throwing them...ha ha ha ha ha ha thanks you guys.. post my results when i'm done.... Brent

Yes, I assumed that it was fluttering with the ignition on since the engine isn't running yet...at least not without pouring gas down the intake.

This is from your original post:

"As i dug around under the seats I found 3 electromagnetic pressure actuators there."


Interesting, are these EHA's you're referring to? I've read some threads the state if these are not correctly adjusted the fuel system will not work. I'm wondering if the previous owner messed with the adjustment inside.


For what it's worth, here some EHA information I found a while back and saved:

"According to the web page maintained by Mercedes owner in Japan, he has disassembled several broken EHA's and found that there are two valve settings, one is 6 and 1/2 turns back from the end, and another is 5 and 3/4 turns. Just try both before buying new one."

dont think he did any adjusting to them.. looks like he just bought them from the junk yard and stuck them on. they all have the paint pencil marking like they do from a junk yard. don't know which one for sure was the orginal so i stuck the one of that didnt have any paint markings on it. and i guess i'm calling it by the right name. its the only electrical hook up on the back of the fuel distribution.

Yes, then that is the EHA. The previous owner must have gotten quite involved to start looking at EHA issues.

For reference, 190E 2.3 won't start thread....EHA issues:

Pulled the injectors out and hooked the lines back up to see if i was getting any spray or anything out of them. I got nothing. guess something is wrong in the distribution. also too look at this injector this is all the came out but my book shows a cone shaped seal that goes along with the one that is on it. Is that the case? actually it shows the one that is on the injector now, a cone shaped, and it looks like a regular o-ring

Yes, it sounds like something is wrong with the Fuel Distributor, providing you're getting the correct pressure and volume at the input.

How about the EHA Valve? I've read where some have experience a no fuel conditions due to it being faulty. Maybe the previous owner turned the EHA adjustment screw and got it out of spec. Hopefully another member will reply to this post that has Fuel Distributor experience.

Have you removed the Fuel Distributor to verify that the plunger is moving properly?

If I remember correctly, the injector seals I replaced on my '93 2.3 looked like the one in the attached photo.

I was kinda hoping the injector was missing a seal. ha ha ha. thought i was on to something. I have another FD that came with the car and two more EHA valves. So I guess i'll swap to another EHA valve with the FD that is on there. Then try it. If that doesn't work swap the FD out with the spare and repeat the process from above. But I'm thinking I'm doing the same as the other owner did and maybe I'm missing the same thing he did. But not sure if he caught the fuel hose or not. I've searched other members post for info on the FD and can't really find a whole lot. It seems that we have hit a wall..Well on the bright side, I've finally came up with a name for the car (grandpa always said it bad luck to not name a car). It's name is DAMMIT. Kinda of fitting. ha ha Post my findings later

DAMMIT needs fuel!

HA HA HA...you got that right...But heres my newest find Dave.. I did like i said I was and I swap the FD with the spare and what not.Interesting enough I got nothing out of the spare. Walked around talking to myself going over every possible scenario. So I decided to put the first FD back and put the oldest looking EHA on it. Guess what.. I got fuel from the top of the FD. So I thought I would try to bleed the FD lines to the injectors by just opening the lines at the injectors and by cycling the key. I did that until fuel strarting spraying out of the lines. I did all four lines the same. And all have fuel coming out for sure. Thinking that I had been blessed by the Mercedes God, I tried starting it. Well Dammit lives up to its name. Nothing happened. So going back to what you had me do earlier, I pulled an injector out to see if it would give me any signs of fuel. It didn't. I'm not getting any fuel through the injectors. I checked the line again and have fuel in it. Which leaves me to believe the injector is stopped up. My question to you is; Do you agree with me on this lastest find? And is there anyway to clean or soak the injector just to try? They look new but I think old fuel has sat in them and gummed them up or something. Or am i getting off course and need to be looking somewhere else? sorry for the novel just trying to give you a good feel of whats going on. Thanks Brent

The injectors have a set pressure before they will start spraying. You maybe now getting fuel out of the top of the FD but is the pressure enough to operate the injectors?
How is your fuel pressure regulator? Have you changed that yet?
The EHA only regulates enough pressure between the upper and lower chamber of the FD to cause some enriching or less rich mixture during engine operation. Its operation is regulated by the ECU which in turn gets info from the heat sensors and O2 sensor to regulate the richness of the fuel mixture. If the OVP is blown the EHA has no effect. The injection system will work just fine - without regulation.

No Ivanerrol, haven't replaced the regulator yet. But that makes pretty good sense. I was just thinking that the injectors maybe be gummed because everything else has been. Is there anyway to check the regulator? The OVP is working proper. I checked it a couple of days ago, SLK230red walked me throught that.

I haven't seen any threads that indicate a fuel regulator fixes a no fuel at injector problem, but you would think it would happen at some point.

Also, since you purchased the car with a 'no fuel at injectors problem', and you seem to be making progress, you might want to try pinching off or blocking the Fuel Accumulator hose that goes to the gas tank. At least this will ensure that you are getting all of the fuel and pressure to the Fuel Distributor.

Fuel delivery test from my manual:

Specification:

1 liter in maximum 40 seconds at a minimum
voltage of 11.5 volts at the fuel pump.

If the delivery is less than 1 liter in 40
seconds, test the following points:

a) Test voltage at the fuel pump. Specification
at least 11.5 volts.

b) Check that strainer in supply line fitting of
fuel distributor is not blocked.

c) Check fuel lines for restriction points
(pinched lines).

d) Clamp off leak line between fuel accumulator
and fuel suction hose. Re-check fuel
delivery. If the specified delivery quantity is
reached, replace fuel accumulator.

e) Replace fuel filter.


Just a thought....keep reporting back Brent. Curious minds want to know.

Dave

I would be sure that the fuel pump is continuing to run when it starts. It gets a signal from a crank sensor. Without this signal I believe it starts and then quickly dies. Or even better as suggested rule out the fuel pump by removing fuel pump relay and bridging the neccesary terminals.
Am I right to think you can increase the pressure to the injectors by pushing down the flap in the air intake? So if someone will turn the key for you, you may be able to use this method to keep the motor running, instead of pouring fuel in the intake. It may be possible to rule out clogged injectors etc this way or at least get a better idea how things are going?

Oh in case you didn't know how this Jetronic system works - interesting:

that's so cool!

good luck

pentoman, I see what your saying. will go through your suggestion. Thanks for the ideas. Didn't think about crank sensor. hummmmm

Dave, I'll keep reporting back. Everyone around here has given up talking to me about DAMMIT. So you guys are my only vent..ha ha ha ha ha,. Will go do what you suggest and let you know what happens.


Anyone else has any ideas lets hear them. Maybe about fuel regulator issues that may give similiar conditions

I'm surprised nobody to date has mentioned a faulty Coolant Temperature Sensor would certainly add to your woes
