2004 1.8 TDDI
102,000 miles
Hi diesel gurus I have an annoying problem which only happens on start up from cold. Basically if you can imagine for anything between 2 to 25 min the van sounds like a bag of spanners. It hunts on idle, it has a very loud diesel "rev" and sounds unlike a normal full sized transit. This happens every time you leave the van for a few hours then almost as if nothing has happened it sorts itself and runs like a dream. You can sit in the van and wait till the engine note changes then like I say it runs with no knocks, smoke and drives fine. I drive it on warm for anything up to 150 miles and no problems.
Ive changed the fuel filter, oil and filter, ECT sensor, cleaned EGR and cam belt (after problem started) all with Ford parts. All pipes and hoses are clean and in good order
Its as if there is a cold start valve or its overfueling on cold but could it be fuel pump?

Any fault codes ?

Does sound like pump timing is miles out when cold.

Fuel injection timing solenoid
Is the likely suspect
But everything else would need checking injectors,metering valve,supply etc....
Vehicle of this age it could all be knackered

Ouch
Ok what's the way ahead then ?
Get the timing re-checked again? the old belt that was removed looked as if it was timed ok but might still need checking.
The van is a great runner when the temperature comes off the bottom so I want to keep it even at the expense of a new pump. Rhubarb when you say the pump timing is miles out when cold I thought pump timing was pump timing not hot and cold?
KarlB is the solenoid the same type of thing on full size transits in the centre of the pump between the injector pipes? and I take it new pumps need to be programmed?
I have a transit specialist near me but want to go armed with a few solutions
thanks for all the replies so far

It's a chain from crank to fuel pump. Maybe your cam timing is out , but likely if it was like this before replacement The pump timing is monitored by the PCM via metering valve,temperature and pressure No it's on the bottom of the pump, This is the vp 30 pump on these tddi vans ( with well know fails ) Your transit specialist should know these quite well. But will want to check over before binning the pump. Used to be about £500 for a exchange ford item , although no longer available now Plenty of diesel specialist overhaul them

KarlB
pump timing is from Cam to Pump via belt??
Used bar and crank pin, undone tensioner, slipped belt off, changed tensioner and replaced very easy job.
if it was timing then what I cant understand is why does it run so good after 5 min ?
ill check it again for fault codes today and post reply

This type of fault is not easy to explain over the net, but from your posts it sounds like a similar problem I had on a Vauxhall, loss of power and very rough engine running for a few minutes and then something clicked into place and all is fine . Using dealer lever diagnostic equipment I could not find any codes directly but did manage to find some problem with the cooling system temperature circuit, having cleared those codes I gave the car a really good road test to get it fully warmed up (diesel) and I did a reprogram using the car pass and since the car has been fine

Thanks Mac
They alter it from hot to cold ?

Thanks Mac They alter it from hot to cold ? Yes , but you say it can last for a couple of minutes to 20 +, i would first get this on a scan tool that can look at the pump data and engine position , any stored codes would maybe give direction, it could be anything though if its diesel clacking noise......

Hi Guys OK
here are the scan results
P0149
Fuel Timing Error
P1564
Injection pump control module requesting reduced fuelling
So I take it from that the timing has somehow slipped and needs setting up correctly?

Stop trying to think the " timing has slipped " You've been told how timing is controlled
