Hi All,
Help please... I'm very confused. My 300CE 24V M104, 91reg with a distributor cap.... There is no power to the fuel pumps and they are not charging when the ignition is turned on. So I assume the fuel pump relay is Kaput, which seems fairly common....
Trouble is, despite reading lots of threads, I am at a loss as to which relay is the fuel pump one!
I have taken out the relay behind the fuse box, part number 201 821 00 47, but see it advertised as a hazard relay on different sites, but it has pins 30 and 87 which are also described on here as shorting out the power to the pumps?? (Not tried due to doubts)...
I also have the MAS relay from behind the battery, part number 011 545 82 32... another thread says that the MAS relay also controls the fuel pump on late M104 models.
Can anyone tell me whether either of these two relays is the culprit..
Thanks for the help in advance.
Phil
