2.2 Hdi Starting Problem. +

[Stuart js]

Hi

Can anyone throw any light on this one.

My car is a 2003, 2.2HDi auto, 139,00 miles

Eloy filled up twice so far, about 10-15,00 before next.

Original Particulate filter.

My problem is:-

I fitted, about 18 months, ago one of these devices that plays around with the fuel pressure in the injector rail, without any problems, fuel consumption went from 43(max) at 70 mph to 52(max) at 80 mph, in town was better than before as well.

 

Then recently it refuses to start, turn the key - nothing - turn off - wait 10 seconds - try again and we are back to normal as if nothing happened, does this cold & hot, maybe once or twice a week.

I thought the fuel device was playing up so I took it off, wah-hay, service lights, anti-pollution fault, get home mode the works, so I reconnected the device, drove better but still had all the lights up, I then filled it up with diesel, as I know removing and refitting the filler gap squirts some Eloy into the tank & resets the anti-pollution system, car now drives and behaves as before BUT very occasionally it won't start.

When I use the on board diagnostic (Colour LCD) no faults shown.

Can't complain, good millage and still with the original Particulate filter.

when you say it wont start do you get ignition lights on the dash then nothing when you try to engage the starter or is there literaly nothing at all no ignition or starter

Nope, everything works, spins over like no tomorrow but just won't fire, which being a diesel is a bit weird!

When you switch on can you hear the pump in the tank?

When it does this does the engine pick itself up to fire like 1 then 2 then 3 cylinders or does it fire up instantley also is there any smoke when it fires up

Thanks you but.......

 

Johndouglas - I do not know as I have not tried to listen to the pump in the tank, when it happens I am not in the position to listen as the next time I try to start it does

 

coastline taxis - No smoke and starts up normally with out any misfiring or spluttering

 

Me - It is as if the immobiliser is still being activated. but how do I check?

Just a note - I had a run o 100 miles the weekend average of 65 mph fuel at 49 mpg - still running sweet.

 

Thanks all

Hi all,

Update to my problem, this may help someone else.

 

Week ago I found the intermittent fault, no power going to the primary fuel pump, checked the fuse and this seemed ok, however, having owned an XM, I decided to spray clean the fuse box and connectors - I bought a service spray from Maplin Electronics - put it all back together seemed fine for a couple of days the the problem came back, so I went deeper, I then done the same thing to the ECU connectors and while I was at it decided to the do the Air flow-meter + air temperature sensor connector as well.

 

Since then all has been fine - No problems.

 

:lol: :D

Seems I spoke to soon, it has let me down again twice now, all I do to start it again is lift the Relay/fuse box cover (back left hand side of engine bay), push the connector with the PINK wire going to it, then it starts

Info - Spoke with man at Citroen dealership and he has heard of the boxes going faulty before - his garage actually has two in stock!! - I will investigate next weekend to see if thre is an obvious connection problem if not it will be a replacement box at £115 + vat - MMMM :(
