Please help me with this one. I'm about to burn it. I have 93 300ce, car was running, but now is a no start. I suspect fuel pump, ovp, fuel pump relay (kickdown relay). I have looked and searched via this forum and many others, but to no avail...When I look at the wiring diagrams from the russian site, none of them match my car...It says I have a mas module, but this car doesn't have that, my 95 has it but not this one. I have tried several years, models, anything I can think of to get a cross reference on wiring... I need to be able to test the ovp, kickdown relay, and fuel pump, but the wiring and pins don't line up. Heres the ovp (000-540-67-45) pin breakdown_
1-Brown
2-Black-White
3-Red-Pink
4-Red-Black/double wire
5-Red
6-Red-Blue/double wire
7-Blank
8-Blank
9-Red-Yellow
Heres the fp (kickdown) relay (003-545-56-05) pin breakdown_
1-Brown
2-Yellow-Green/double wire
3-Blank
4-Blue-White
5-Red-Black/double wire
6-Black-White
7-Blue-Green
8-Blank
9-Blue-Red
10-Red-Blue
11-White-Blue
12-Blank
I'm confused because nothing is lining up, and I don't hear the pump or pumps. Does this car have two pumps like cis-e? Please send me a MB angel to fix this car, or atleast send me in the right direction. The ovp and fp (kickdown) relays are not cheap, and I want to make sure whats wrong before I throw parts at it. Thank You!
