'99 and '05 E55 AMG
This puzzled me a bit until I realized you had a non-AMG but were posting in the AMG section. Completely different pinouts and wire sizes/colors between the two versions. On the non-AMG, connector 1, pin 3 has a 2.5mm cross-section red-green wire connected to the fuel pump on the right side. The AMG has a 0.75mm cross-section red-white wire at that location.

Replace fuel pump. Replace fuel filter. Replace fuel pump relay (lowest one on the rear SAM). Verify fuse #4 on rear SAM is 15 amps and that the blades have no corrosion. Obtain new connector and sockets from dealer, aftermarket electrical supply, or from donor car in salvage yard. Repin the connector (do NOT attempt to reuse that burned/overheated socket in that connector). Thoroughly clean the pins on the SAM (assuming SAM is still good); if SAM is burned out, obtain a replacement and have it coded for your car.

In future, replace fuel filter and pump on regular basis.
