My vts was running fine then on way home it started missing at bout 30mph no eml light on. Now car won't start dash lights are flickering and a strange noise coming from the ecu. Best way I can describe the noise is like the noise a printer makes! Helpppp
Help please

#2Relay under the ECU has died by the sounds of it
-
#4as far as I'm aware, there are only 2 relays.
brown and black.
the black one on my 1.5D works in my GTI. so I would assume a VTR will have the same one. (don't ask why my 1.5D has one i've not got a clue) -
#5Is it the fuel pump relay? How would this coz the car not to turn over
Tried a vtr one in it and it doesn't make a difference :-( -
#6Oh I missed that lol
have you checked your gearbox earth? if it's loose that would stop the starter from turning. -
#7The relays where the noise was coming from tho
-
#8Does the pump prime? run a live from the + battery to the 2 pins in the centre of the pump to see if it whirrs
Check the fuses (Red 10a i believe)
Try another relay
Pull the fuel line off and turn it on the second click to see if its pumping fuel
Check earths
Get a diagnostic on it
..and if you want go there with it pull the fuel rail off and see if the injectors are pulsing (squirting)
Check coilpack sparks
Plenty for you to check1 user thanked this post: -
#9Cheers it doesn't even turn over the noise its making is defo coming from the relayQuote:Does the pump prime? run a live from the + battery to the 2 pins in the centre of the pump to see if it whirrs

would that cause it not to start? It didn't sound like its prime . I tried a vtr one but just did the same what earth will I check -
#10Well change that? Yes i believe so. pump and spark *i think
Earth on the gearbox
It *should* make a noise on 2nd turn of the key. Run a live to it to see if it works. Are you sure that other pump works? not faulty.
Failing the above phone someone to come out. It will save you the hassle and money and time because its just guess work on a forum. I'm no mechanic so i'm just going off what i did myself. (recently had a similar problem but sorted now). -
#11Check the voltage at the battery, sounds like your alt has given up and the battery has gone flat
Failing that it could be the ignition relay or an earth strap given up
But check the battery first, things spazz out when it's flat -

#14But it's not a fuel pump relay lol.. On cars with a pump it does control it
It's the ignition relay, it turns on everything with the ignition
It's like the 3 plug diesels lol, only two of the plugs are actually used but its still a 3 plug ecu
-
#15fuel pump makes humming noise on second turn I tried to get a new relay the day from a couple places here but said they couldn't get one! Phoned Citroen and they said they had to many different relays and that I will have to take it in shop tomorrow so they can see it!Quote:Well change that? Yes i believe so. pump and spark *i think

#16I've got a 3 plug diesel.Quote:But it's not a fuel pump relay lol.. On cars with a pump it does control it

Earlier models don't have an "ignition" relay. You've forgotten there is no ignition on a diesel either. There is a single stop solenoid and an immobiliser board
The point is, there's practically no function and there's no need for it to be there.
Hell, the immobiliser is still part of the pump on ECU models, 1.5 diesel ECU's aren't coded. -
#17So is the relay under ecu a fuel pump relay or ignition relay?
-
#18Citroen will pull your kegs down and bum you on the price of a new relayQuote:fuel pump makes humming noise on second turn I tried to get a new relay the day from a couple places here but said they couldn't get one!

No scrapyards? -
#19Went to scrapyard only one vtr took relay of it but it never worked no vts
-
#20Anyone have a spare relay for vts ;-)
-
#21Had car diagnostic today turns out its earth from gbox to chassis will try sorting the night and report bk

#22Forget ignition as a term, and think of it as switch, there are still things to be turned on when you turn the ignition on, hence the relayQuote:I've got a 3 plug diesel.

I get your point but the looms are all closely matched, easier to keep the same for the little amount it'll do then design a diff loom that doesn't incorporate it -
#23Its the earth from bat to chassis that was snapped
-
#24She's alive!

#25Good stuff. Diagnostic is the best way to get to the bottom of your problem. Like i say its just guess work on a forum. It does help but it can also cost you a fortune if you take what everyone says lol.
-
#26But the pre 2001 diesel with Bosch (or Lucas) pump didn't have one.Quote:Forget ignition as a term, and think of it as switch, there are still things to be turned on when you turn the ignition on, hence the relay

So a differently designed loom was already in place. only difference is the ECU which doesn't do anything at all. except monitor battery voltage and engine RPM. it does nothing with the data.

#27My post was close enough
(#6)
Peugeot charge £80 for a diagnostics testQuote:Good stuff. Diagnostic is the best way to get to the bottom of your problem. Like i say its just guess work on a forum. It does help but it can also cost you a fortune if you take what everyone says lol.
"Oh we can't read your ECU" "there are no DTC's stored"
ORLY why's my ABS light on then. knobbers. -
#28Yeah get someone out with a Snap on one.

#33I know what you're saying..but things become obsolete when new processes come in, costs more to keep them like that, they control stuff like the pas if you have it and the actual power when you turn the key etc and so onQuote:But the pre 2001 diesel with Bosch (or Lucas) pump didn't have one.

So not totally useless
New loom dictates it run that way
