Hello, my name is Kris, Big thanks to bba-reman and all the help they have given me in the past and Big thanks to all that contribute to keep vehicles out of the scrap pile. new member to this forum but have found some helpfull info on here before.

so i have been asked to help with a Citroen dispatch which is proving to be a bit of a pain. The van was parked up in the yard, as the owner walked away from said van he noticed a relay clicking type sound, bit odd as it all off and locked up. next day the van would not start. its '53 plate 1.9, and the vin is vf7bzwjyb86053606 (for eng. code purposes) I checked for live feed to glow plugs, asked him which relay clicking, no helpfull info from owner, so i (incorrectly) presumed glow plug relay at fault. i replaced it but still no feed to glow plugs, noticed no glow plug light on dash and also no eml too. simple diagnostic machine showing link error. bit of internet searching revealed info regarding the common double ignition relay probs.

if i physically connect the two thick wires at glow plug relay, one live and other to glow plugs to get glow plugs hot the vans starts, runs rough though, sounds as if diesel pump advanced.... but it meant i could get it closer to workshop. so i presume the ignition relay is not 'powering' up the management side of things.

with the ignition on, if i disconnect relay and connect again, i am getting a click but not sure its both parts of relay working, so replaced it (bitron/ omron 240107) .... no change) i've opened up some of the loom close to ecu/ replays, no obvious probs. cleaned/ checked for earth at earth points. checked ecu connection for visual probs, nothing obvious. checked fuses, all o.k.

so without wiring diagram/ test data, i'm now a bit blind if you like. i read on this forum, a '51 peugeot 2.0 hdi with similar issues and same ign relay (?) first check was for 'permanent live on relay terminals 3,8,11 and 15' ....... on this citroen, all live but nothing at terminal 3 (relay dis connected) connect relay and terminal 3 goes earth (if my memory serves me correct)

sooooo i'm so close to try making terminal 3 at relay 'live' to see if it springs van into life but thought if best to get second opinion first.

its an old van and can be scrapped without too many tears but its always good to keep things running if poss hey. Many thanks for looking

Fair comment on the WD ... will seek one out via local garages autodata and will study to find a difference. but im not convinced any code reader will read as seems ecu is dead to the world of 'citroen dispatch' Laugh prob wrong but just seems engine management not powering due to ign relay for one reason or another.... will report what i find. many thanks

o.k makes sense when you put it like that Smile ..... would snap on reader fall under 'manufacturer specific'? excuse me..... i grew up on either a snap on or launch covering most bases but understand a lap top and the right software will knock socks off ..... pon right application. i can reel snap on in for a code read but will owe favour in return but if this next step...... damn worth a looksy. thank you Rob Wink

Just to add .Ive had in the past glow plugs that were non gen which had higher resistance shut the the relay.
This wont be your case if they have not been changed.

I back up what Robski has said get it read and live data check with Lexia by some-one who knows how to drive it, not just a code read jocky.

As for Snap-on on a french car Crying

Hi guys, o.k ...... well i don't doubt you. thank you for the advice. Lexia weapon of choice then. trouble is i don't think the owner will be up for paying someone to 'read' it..... sure he'll just scrap it, but will have a chat with him. i was just trying what i could to help him out. i may be very wrong but seems ign relay not powering stuff up. with relay dis connected and ignition on the terminals show this with a probe.... 1. earth (but very faint) 2. live 3. nothing 4. nothing 5. earth 6. nothing 7. nothing 8. live 9. no pin 10. earth 11. live 12. no pin 13. earth 14. live 15. live

if i switch ignition off .... all the same except terminal 2 shows earth.

as far as i can make out terminal 3 should be live? was just thinking if so i could run a live to that terminal just as last ditch attempt to save it.

i usually only take on stuff i know i can do.... as i work on my own and don't require as much income as most people. but am open to have a go..... also its stuck outside my shutter doors Laugh

Many thanks for your input and will always recommend bba- reman. have a nice friday all.

Kris

IF you're 100% certain term 3 should be live then you could try that. But cut/disconnect the wire to it first because you don't know what else you're making live if you see what I mean. And, I haven't looked at a WD myself but I'm guessing you now have, where should that live feed come from?
But I can only suggest that if you're positive that the terminal should be, well, positive.
