Update:
I put a cut up coat hanger wire (resistance tested good) bypass fuel pump relay on pins 30 and 87 holes/connectors. See the picture.
With the ignition turned on, I checked the two wires connectors to both fuel pumps to determine if there is any voltage going through using multimeter. Nothing shows up. However, checking the resistance on both fuel pumps (electrical 2 wires connected to the fuel pumps) with igntion on, it showed at 2000 ohms, 005 resistance at the front and the rear fuel pump by the fuel tank shows at 2000 ohms, 006 resistance.
I, then, proceeded to ignition start and the next thing happened was the wire on the bypass fuel pump smoking. Also, smoke coming out of the 30 amp thin fuse box (see picture) and under the fusebox near the oil filter. A little electrical fire started and I put out the electrical fire under the fusebox with water. I checked and rechecked to make sure the fusebox area is clear of any smoke/fire and elsewhere. Wow, that is something!!!
Any chance of the issue above repairable? I have another identical 1994 E320 wagon without the ASR. I can swap parts that needs to be replace to make my 1994 Mercedes wagon working again. I first need to know what to do next. Did anyone out there have this similar experience? If so, how did you repaired/fixed this problem? This current issue is way way out of my league of knowledge to fix/repair. Comments, advice/feedback is greatly appreciated.
