tony pashley Posted May 22, 2003 Share Posted May 22, 2003 Have just taken a call from Angus (as in angus&tessa) - stranded in pub car park awaiting AA tow truck... He suspects failure of ''MFU'' (don't get those on my XFlow!). Is there anyone in the area of Egham or Englefield Green who would be free to call around to Angus in the morning (Friday) so he could try out your MFU as a check, before he goes out and buys a new one? If you can help him out, he's going to be up late tonight - his mob. number is 07946 471717 - please give him a call - his PC is on the blink too, so he may or may not see BlatChat... Decent coffee and hospitality will be available! Many thanks. Edited by - tony pashley on 22 May 2003 23:56:48 Link to comment Share on other sites More sharing options...
caterhamnut Posted May 23, 2003 Share Posted May 23, 2003 All sorted!! Many thanks to Tony, and Geoff (Miraz) who responded within about 10 minutes! Easy tow home, almost certainly the MFU which warned us a few weeks ago that it was a bit dodgy - should of replaced it then!! Thanks to all at Walton for their support in car park - there was no way we could of fixed it there - thanks to Adil for giving Tessa a lift home! Incidently, symptoms were turning the ignition key to have nothing happen - ignition light came on, but then nothing - not even a click. At first thought it was starter, then perhaps the imobiliser, but obvious clue was that there was not the normal buzz from the fuel pump pre-ignition, and the main relay for that is in the MFU (black box under the Rover MEMS ona 'k'.) 😬41,000 miles in 21 months! angus@tinyworld.co.uk Caterham pics here Link to comment Share on other sites More sharing options...
I.Mupferit Posted May 23, 2003 Share Posted May 23, 2003 And wasn't it an interesting lesson last night, if anybody needed it, that you can't always judge people by their appearance Mind you, having said that, has anybody heard from Chris & Margaret this morning 🤔 😳 Only joking!

Leadership Team Mcalvert Posted May 23, 2003 Leadership Team Share Posted May 23, 2003 Angus, Tessa, What time did you finally get home last night - Sorry we ended up leaving you waiting for the RAC, but we'd long exhausted anything useful that we could add... Take care - Michael. Link to comment Share on other sites More sharing options...
Chris W Posted May 23, 2003 Share Posted May 23, 2003 Angus I think this is possibly a connector problem on the MFU. Have you made sure that the two connectors on it are pushed fully home? For the starter not to turn over AND for the fuel pump not to operate, TWO relays would have to be dicky in the MFU. This is not impossible but unlikely to have happened simultaneously. It's more likely that one or other of the 2 connectors is not making contact. Suggest you pull them off and reinsert them first before spending out on a new MFU unit.

F355GTS Posted May 23, 2003 Share Posted May 23, 2003 ECU Fuse? Mark Link to comment Share on other sites More sharing options...
Chris W Posted May 23, 2003 Share Posted May 23, 2003 My brain must be in the fridge today.................... yes, the ECU fuse would also give Angus the same symptoms and is a much more likely cause. Well spotted Mark. Chris 1.8K SV 140hp see it here Edited by - Chris W on 23 May 2003 12:23:15 Link to comment Share on other sites More sharing options...
caterhamnut Posted May 23, 2003 Share Posted May 23, 2003 which one is the ECU fuse - where is it? My fuse box 'aint like the one in the book!! cheers all for advice - bl**dy electronics. 😬41,000 miles in 21 months! angus@tinyworld.co.uk Caterham pics here Link to comment Share on other sites More sharing options...
Chris W Posted May 23, 2003 Share Posted May 23, 2003 Angus It will be a 20A or 30A fuse and it will be the one that's blown... if indeed it has. If you find the blown 20A fuse replace it with a 30A fuse and all should be well. If all the fuses are OK, try reseating the MFU connectors as previously suggested. good luck Chris 1.8K SV 140hp see it here Link to comment Share on other sites More sharing options...
Tony Whitley Posted May 23, 2003 Share Posted May 23, 2003 The fuse on mine is the right hand one of the pair that's separate at the top. Tony M1 7 SMW 1.4SS Lotus colours with cycle wings.

caterhamnut Posted May 23, 2003 Share Posted May 23, 2003 yep - you are all right! ECU fuse blown, replaced with a 30A version, car starts no problem. Fuse was blown in a very 'subtle' way - had to look closely to see it - certainly closer than we looked in a dark pub car park with two or three key-ring torches! cheers for the help! 😬41,000 miles in 21 months! angus@tinyworld.co.uk Caterham pics here Link to comment Share on other sites More sharing options...
Chris W Posted May 23, 2003 Share Posted May 23, 2003 Angus You can buy a test screwdriver which actually has a small silver oxide battery and an LED in it. These are great for testing fuses especially in the dark. You hold one leg of the fuse in your fingers, touch the screwdriver point to the other leg with your other hand and touch the index finger of the same hand on the contact button on the other end of the screwdriver. If the fuse is OK, the LED lights up. Really useful too for household mains fuses (unconnected of course!!) which are not transparent.

Graham Perry Posted May 23, 2003 Share Posted May 23, 2003 So what looked like being an expensive repair turns out to be about £1 to fix. Thats the power of blatchat. Well done all. Link to comment Share on other sites More sharing options...
billywhizz Posted May 23, 2003 Share Posted May 23, 2003 Yep,I,ll second what Graham said ...and like Chris says get a continuity tester or you,ll curse the next time you need to check a fuse.A really helpful piece of kit brakepedal ! what's that for then?

caterhamnut Posted May 23, 2003 Share Posted May 23, 2003 exactly - I bet Blatchat has saved people a fortune on wasted time/new bits etc through the advice and help people get on it - of course, that fortune then gets spent on upgrades which we all then talk about on Blatchat screwdriver looks like a good buy 😬41,000 miles in 21 months! angus@tinyworld.co.uk Caterham pics here Link to comment Share on other sites More sharing options...
