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.

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.
