Question about 1990 Mercedes-Benz 190
This is probably the relais. You will find it as a black box behind the plastic cover which is located behind the battery.
I remember the bones 87 and the one infront were the responsible ones for the fuel pump.
Thus disassemble it and test the three small relais you will find inside.
