davestarcraft Posted November 21, 2019 Share Posted November 21, 2019 Anybody know where fuel pump relay is located on a CSR 260? Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted November 21, 2019 Member Share Posted November 21, 2019 I’ll have a look for the layout when I get home. And it’s probably in http://www.sjmmarsh.f2s.com/7documents.htm.Jonathan Link to comment Share on other sites More sharing options...
NeilCSR Posted November 21, 2019 Share Posted November 21, 2019 Isn't it part of the MFR? Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted November 22, 2019 Member Share Posted November 22, 2019 I find it very hard to know what to look for when the documents don't say "CSR 260" precisely. From the 2016 Handbook:Does that match? JonathanPS: If you'd like the Assembly Guide and Handbook, please send me a Private Message with your email address and details of the Seven. But Steve's site as linked in #2 above probably has more than I do. Link to comment Share on other sites More sharing options...
davestarcraft Posted November 22, 2019 Author Share Posted November 22, 2019 Yep! Found it, it's in the MFU Link to comment Share on other sites More sharing options...
NeilCSR Posted November 22, 2019 Share Posted November 22, 2019 Good news....They aren't too expensive to replace, standard Rover unit (or are on mine - 2007 vintage) and also quite easy to replace as well if there is a problem.Neil Link to comment Share on other sites More sharing options...
davestarcraft Posted November 22, 2019 Author Share Posted November 22, 2019 The CSR doesn't have a fuel pump relay in that block it's in the MFU. I have a .pdf for the CSR thank you Link to comment Share on other sites More sharing options...

David aka Blue7 Posted November 22, 2019 Share Posted November 22, 2019 MFU ... qu'Est-ce que c'est ?Multiple File Uploader?Multi Functional Unit?Middle Finger Up?... and where is it? Link to comment Share on other sites More sharing options...
SM25T Posted November 23, 2019 Share Posted November 23, 2019 Multi function relay unit on my Rover engine car. It is on the bulkhead in the engine bay above passenger legs. But it could be anywhere on a different model. Black plastic about 150 x 80 x 40mm Link to comment Share on other sites More sharing options...
David aka Blue7 Posted November 23, 2019 Share Posted November 23, 2019 Thanks for the clarification. I have never heard of that unit being referred to as an MFU, it is always generally described as the fuse box. Under the heading Fuses and Relays, the handbook describes "them" as being located in the fuse box, there is no mention of an MFU so although technically correct it is nevertheless confusing especially when they are located side by side and covered by the fuse box cover.To add to the confusion, as far as I am aware, CSR's do not have a relay for the fuel pump, they normally have 4 relays, horn, lights, hazards, flasher and a fifth if you have a stack dash. The fuel pump is protected by a fuse, normally "M" (or no. 13), which is 15amp.Jonathan's diagram above is certainly shown in the last / latest CSR handbook on page 46 as fig. 28 but although listed under Duratec it isn't the CSR layout, which I have always found misleading (but very Caterhamesque). There are two Duratec specs. shown and fig. 28 is for the first Duratec listed with 6 relays and not other one listed Duratec 175/237, which has only 4 relays. There is further confusion in that the latter Duratec 175/237 relays are shown as being for Starter, Ignition, Reverse, Flasher, which is different to my CSR. The Earlier CSR handbooks were different and in all three of my CSR's, from 2008 to 2015, this has been the layout:If you look at the CSR / SVR loom assembly diagram in the link that Jonathan provided above you will see that the CSR only has 4 relays:So if Dave has found a fuel pump relay in the fuse box "MFU", it beats me as to what type of CSR this is ... unless you mistakenly referred to relay when you "relay" meant "fuse"?

NeilCSR Posted November 24, 2019 Share Posted November 24, 2019 MIne does have an MFU / MFR / MFRU / 'Squarish black box' or whatever you want to call it. And it does have relays inside. It's not on the wiring diagram pdf that I use (nor is the ECU) but - having had problems with the fuel pump relay previously - it's there....The other relays - stacked next to the fuse block are quite different, identified separately on the loom wiring layout. The MFR is beyond the 'Grey Engine Plug' which isn't covered on this diagram. From the Fuse Key, F13 (YG) feeds to P9 on this plug.Neil Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted November 25, 2019 Member Share Posted November 25, 2019 Is this diagram on Steve Marsh's site consistent with any of that CSR-specific wiring?Jonathan Link to comment Share on other sites More sharing options...
NeilCSR Posted November 25, 2019 Share Posted November 25, 2019 Hi Jonathan,Quite likely, I'd looked at the diagram above and interpreted/assumed it to cover a segment of the MFR (Fuel Pump relay), - identifying pump as 'PCM' and the fuel level sender as 'FTL' - and the pump/sender unit so bridging a segment of the overall wiring loom diagram and part of the MFR. No colour coding for wires, just the schematic.Neil Link to comment Share on other sites More sharing options...

NeilCSR Posted November 25, 2019 Share Posted November 25, 2019 Arrowed.....: May be in a slightly different position in the 260 but in (my) 200 it's just in front of the heater.Neil Link to comment Share on other sites More sharing options...
