Fuel Pump Relay Miasma
My manual Euro 1988 300CE is running poorly and often won't start. I have replaced a number of ignition and electronic components to try to get it right or at least narrowed down -- plugs, cap, rotor, wires, OVP, CPS. I found a quirk in the part numbers for the fuel pump relays. The OEM original relay is part number 002 545 51 05. Any search for that number or a model or VIN search brings you to a superseded part number 003 545 24 05. That is the same part number for the US cars. However, There appears to be a difference in the relays.
The 002 545 51 05 appears to be for cars with manual trannys. The superseded number is used on auto cars and the relay has a kickdown switch in it. I'm not sure what that means electronic wise, but must be making a difference because I've tried the OEM relay from my other (US, auto) 300CE and a brand new Kaehler aftermarket relay from US cars and it won't run with those. When the 002 545 5105 was current, there were two different fuel pump relays in use with W124s with the M103: - 002 545 51 05 6 Zyl. 6550 min KVS, and - 002 545 52 05 6 Zyl. 6550/min KVS Kickdown The current parts lineup does not appear to include two correspondingly different parts. German EBay has several of the 002 545 51 05 relays available used, but are expensive enough with shipping to make me not want to just blindly take those chances. Anyway, just hoping somebody might have some knowledge or data on this issue or a suggestion as to whether the original one is rebuildable and by whom. Thanks.
