Re: [MBZ] 107 fuel system (Jim?)
I am just now getting things thawed out enough to get back to this project from Nov, just before the every other day snow storms hit. ( got snow in my face last sun!) I removed the glove box and the trim panel below the right dash. I did not find much for relays behind the glove box that looked like they fit this description. There were two large relay boxes behind the glove box. One is aluminum cased (about 4 x 4 x 1 1/8), and toward the firewall. Bolted to it is a black plastic cased relay of about the same size. The black one has a 12 pin plug in the bottom. The aluminum one has a 12 or 14 pin plug at the bottom. On the right side, above the fusebox are a series of ice cube relays. I pulled one, and it is a 5 pin plug. At the top of this series is a taller relay that looks like an overvoltage relay with the fuse on top (red cap.) If anyone can help to identify where the fuel pump relay is on a 1985 380SL, I'd appreciate it. TIA. At 09:00 AM 11/15/2007, you wrote: One or two electric fuel pumps under the car at the rear. Fuel filter Should be one in that car, if it's like mine. I think the 560's grew a second one. is adjacent, as is the pressure accumulator. Fuel pump relay is in the kick panel on the passenger side, I believe, but I don't know which one it is... You should find the relay and jumper it to run the pump and see if that cures the problem for a short while. If it does, replace the relay. You should also check the current draw -- a bad pump will roast a relay, and a new one won't last long, either. It's behind the glove box, right side. Black, oriented narrow edge forwards, pins down. (The kick panel has the small relays behind it.) Two rows of pins, one row longer than the other. You jumper across the two pins in the socket like so: A B C D E F G**H I The last two paralleled pins closest to you, leaving the one odd pin out. One is labeled 87 on the relay, the other is, IIRC, 30. Be careful, 30 is hot at all times. I use a switch with two pins salvaged from a wiring harness. I plug in the two pins, then I flip the switch. Should be about 5A or so, if it's like my car. -- Jim Original post: (11/15/07) Subject car is 85 380SL Has symptoms of fuel starvation. My thoughts are fuel filter or fuel pump in the process of dying. It will run fine, then die. After coasting to a stop, it can be restarted. Has a fairly new coil and ICU. (2-3 years old) Could be ignition problem of fuel startvation. AFIK, this car has an electric fuel pump in the rear. I assume there is a fuel filter somewhere around the engine. There is a tank strainer as in Diesels Any other ideas or suggestions. Winter cold is blowing in here, so I want to limit my time outside in the weather as much as possible byt figuring out what and where to check before I go out. Thanks, And forgive me as I am an old Dieselhead. These gasser contraptions confuse me.

Re: [MBZ] 107 fuel system (Jim?)
From the photo on Rusty's site, it looks like the fuel pump relay should be a little smaller than a Klima relay.

Re: [MBZ] 107 fuel system (Jim?)
Nevermind, I found fuel pump relay. It is under the passenger kick panel, staring me in the face. It said 8zyl Kickdown, so I dismissed it as something to do with the trans kickdown circuitry. After I figured out the size and looked again, I figured out it was the one. The other thing that threw me off was that I was looking for an 8-pin plug. This has a 12 pin plug, but only 7 pins on one end are used. Now If I could only get the problem to re-occur when I am driving it. So far it only acts up when my daughter is driving, and I can drive it around and have no problem. Thanks again to Peter and Jim for helping out!

Re: [MBZ] 107 fuel system (Jim?)
got snow in my face last sun!) I removed the glove box and the trim panel below the right dash. I did not find much for relays behind the glove box that looked like they fit this description. The fuel pump relay stands vertically, narrow edge facing you. It's the right-most one behind the glove box, and black, and is similarly shaped to a CC amplifier but somewhat smaller. It is not on the side wall with the fuse box, it is not tucked against the HVAC box. It's labeled with 5300/min 8Zyl.12V, a Bosch logo and 896377, Kickdown, and has what looks like a date code on it.
