I think all this comes out too - bits circled in red. Can someone confirm. Was going to look at 500 E pics of normal engine bay

Now last thing is how to get all that wiring out at the bottom. Is that even factory the square grommets the wires stick out from?

Took a break this morning to check out the FCP Euro car show with the wife. We brought Miss Bee.

After the show dived into- actually under the car and replaced Sauce's WALBRO pump and filter and went back to the dual setup.

Then tonight since wife went to bed early replaced all the spark plugs.

Quick question- does it matter what the orientation is of how the metallic piece is clocked relative to the pump outlet - for the fuel line that connects the 2 fuel pumps?

I think I just answered my own question and confirmed no matter how it's clocked fuel will flow in the cavity- from the picture.

Took a break this morning to check out the FCP Euro car show.
@MY911S,
Was that carshow in the Robinson Helicopters parking lot in Torrance.

BTW, I was in San Pedro w/ my wife Saturday and we ran across a huge car show down by the docks across from the yacht harbor. It was breaking up when we discovered it around 3:30 PM.

Yes it was. Interesting I wonder what the San Pedro event was. I go there a lot. We used to live there and aren't too far away.
 
Well darn. I got all the bits connected including running next door to pelican for a fuel pump cap nut Part #: 123-990-00-53-MBZ and the proper sized hose clamp size only to start the car and...nothing...doesn't turn over. The pumps aren't making any sound and I measured voltage at the terminals an 0 Volts. I assume that the Walbro pump has the same connections and it should measure 12 V between terminals? Any help appreciated. Might try to check for a short and access the relay and jump it next.

In actuality after watching this I'll video the startup and see if i have sound.

Do you mean the starter doesn't engage? That's a different issue not related to the fuel pumps. Or do you mean it cranks but won't fire?

The fuel pumps will only run for 2 seconds when the key is turned on. The LH module triggers the relay below the rear seat. Remove the rear passenger seat cushion, you should hear the relay click on/off when the key is turned to position 2.

You can remove the relay and jumper the appropriate sockets to force the pumps to run. Don't mess up and jumper the wrong pins or you could damage the LH module. Only jump from +12V battery (#30) to the fuel pump feed (#87). Diagram at link below.

 
@MY911S,
Carlo, Is the starter turning over the engine? It doesn’t sound like it to me. Maybe my hearing is fooling me but to me it sounds like a dead battery to me. OR are you just turning the key off before the engine turns over?
 
starter is turning over the engine. cranks but wont fire..anymore. it ran right before i replaced the pumps and the plugs. thanks guys i'll try the above. i stuck my phone under the car...didnt seem to hear any pump coming on at all at any time. Mercedes source also does it this way alternatively

oh sorry if i caused confusion - that's not my car---it's just a sample video--that shows what to listen to (pump sound that's working)
 
So I jumped the relay and could clearly hear the fuel pumps this time- plus it was leaking some fuel at the filter interface which further confirms pumps were not getting juice yesterday when I tried to start him up
 
Ah I thought I had read in this forum that would still work.
Any M119 V8 LH module can be used for testing, from any year/model with LH-SFI engine management (through 1995 USA model year).

The M120 V12 modules are designed to only control 6 cylinders (two modules are used to control all 12 cylinders) and these won't work on a V8 engine.

:rugby:
 
Went to ye old Electronics Store close by after the gum surgery. Will try to to the LH Capacitor RR later.

IMG_8401.jpeg
Stopping by Pelican on the way home for the relay - though I tested mine and relay works. So I have a spare.
 
A little messy with all the conformal coating crumbling off.

Took one large and one small capacitor off. One of the small caps seems bad.

Success. After a few tries and tightening up the fuel filter leak that showed up again, car finally started and holds idle. The accelerator cable needs adjustment or might need another one as I kind of hacked into the one I purchased

Crawled under the car to install these rubber plugs for the fuel pump terminals that finally arrived. Hopefully I can get the car off the ramps tomorrow.

Got some NIB lenses from Sauceman today so might be ready to put the headlights back on. Still deciding if I sell the existing Euro lights or just assemble and have a spare set.

Also need to figure out what bulbs they take.

Car runs but needs adjustment. Idles too high and doesn't shift or super late. Reinstalled another accelerator cable and found this crack in the bracketry.

The plastic arrows are just a visual aid to line up the throttle vs transmission linkages (and, this can be tweaked to fine-tune upshifts/downshifts to your personal preference).

Throttle cable adjustment should NOT have any effect on idle speed! At idle the throttle cable should have zero tension on the linkage and the ETA lever should be fully at rest on the idle stop. Idle RPM is controlled electronically. If adjusted wrong you'll end up with limp mode where the first half of throttle pedal travel does nothing.

:mushroom:
 
@gsxr and thoughts on that cracked piece I circled in red. Also when you say "plastic arrows"
from what picture or stop is that in the procedure? Thank you.
 
I'm not seeing any cracked piece. The plastic arrows are the tips of the metal brackets, see additional red arrows in screencap below.

These plastic tips should be aligned, which they are in your photo. See FSM step 5.1 also.

This is for the transmission control cable adjustment, NOT the throttle linkage to the ETA. Adjust turnbuckle / sliding linkage #2 to increase/decrease shift RPM's, but first you need to get idle speed normal, NOT be in limp mode, and have shift points normal-ish.

What's the point of switching ignition switch on in step 6 only to switch it back to the off position at the next step

IMG_8618.jpeg
 
Hmm I thought the arrows were as explained in this video
Nope. That video is for the CIS-E engine, the throttle linkage is COMPLETLEY different vs LH-SFI. Basically nothing in that video applies to the 500E except the little black plastic rectangle he's replacing, which is the same/similar.


@gsxr Going back to my picture and the circled area - that black tab that looks to be broken in half is actually not a break? It looks like it. Here's a closeup.
Now I think I understand. Those are two separate pieces, you are thinking it is 1 piece broken in half. Move the rearward piece with your finger and it might start to make sense. Those plastic tips should be lined up for the rough adjustment. In the photo, yours look ok, they are lined up within a mm or two? Can't quite tell from the angle of that photo.

:wormhole:

This must be spelling mistake. WOT must be checked with ignition switched ON.
Yeah, something in there is a typo / mistake. With the ignition on, if a second person presses the pedal to the floor (not kickdown), the throttle butterfly should be almost fully open.

With the ignition off, you are checking that the bellcrank on the ETA is resting against the WOT stop. This is the important part, at idle the ETA bellcrank must be resting on the idle stop, and at WOT it must rest on the WOT stop.

Phew what a relief. I should have put more faith in German Engineering than to assume that was per design :)
 
It's looking better. Car idles, a bit rough at the start, smooths out a little when warm BUT the big thing is shifts properly seemingly now. Drove to the gas station without stalling :) Thanks for the key tip @gsxr of checking the stops when at idle and the plastic arrows. I had to shorten the rod slightly about 1/8 of an inch.

Any recommendations for a replacement bulb for the small Osram bulb next to the H4 in the Euro headlight? I went to the parts store and the Sylvania one that looked to be the same size wouldn't fit. It was slightly large in diameter.

The city light bulb is a T4... more details here.
