I'm trying to help a friend solve the stalling problem in the 90 240. When I turned the key I didn't hear the fuel pump prime. When I checked the fuel pump relay, a). It's black - aftermarket, and b). the harness is missing - six wires are attached to it.
The wire colors do not match the diagram in the Bentley Manual. I downloaded a wiring diagram for 1990 240 with the correct wire colors, but it does not identify the terminal on the relay. Can anyone tell me which terminals on the relay (i.e. 87/1, 87/2, 30, 85, etc) the following wires connect to:
Yellow-Red
Orange
Blue-Green
Red
Yellow-Black
Orange
Thanks in advance. With this car, this may just be the tip of the iceberg: the diagnostic module has been removed!
