HDi 2.0 8V wont start when cold - FIXED - NOT - YES

[Northern_Mike]

nothing interesting so far from the Lexia I am guessing chaps? (just wondered what the negative flow correction was on Injector 4? )

Started car again today, with easystart... so a relief now at least I can use it..
Went to fit a new Fuel Filter at lunch, but ECP have sent a slightly different one.. are there two types fitted to HDi's - anyone know >?

answered,., Bosch and Siemens.. learning all the time..
If anyone wants a brand new Bosch filter, I make you a nice price

Can you take a pic of it John? I'll have it if it's the same as mine.

I'm not sure if mine is Bosch or Siemens.. I have Siemens injection but I think a Bosch fuel filter housing. Totally loopy really.

thanks Taffy..

Mike, its got a weird seal (plus a normal o ring), looks like this

My filter has a much smaller bore and doesn't have the weird seal

If Mike doesnt have/need it then i'll take it.

Always like to carry spare filters etc

(my thoughts on yours are do a leak off test but inj 4 does look suspect.)

[Northern_Mike]

No, I don't need it, mine is obviously the same type as the one John needs. I ended up with both last time I did a filter change too. Thanks for looking!

thanks Chris

spent some time today sorting a new garage.. work had a power cut so was no use being there,,
should now at last be able to find some spanners ,,,

Hi John,

Have you swapped the heater plugs?? I find it strange it will go and stay running with easy start. That would sugest little wrong with anything else..

The two types of filter houses is easy to detect: The Bosch one has just TWO pipes in the Top of the houseing and theres a 21mm shape Nut on the top to open the house. The filter for this one has a funny shape on the bottom ..

The other house had three pipes and an Electrical Plug! This filter is round BOTH ends...

hi Paul, like I say not touched anything yet.. for various reasons,, Car runs like a dream and has done for last 18 months,, just cannot start first thing in morning, if the air temp is 5-10C for example,,

.. dread removing glow plugs for obvious reasons, although they were easily my first thought..

I read (all the time) that HDi's don't need Glow plugs till below -5C or more? what are your thoughts?

Is it possible that the relay and / or control for the plugs is broken? I guess I can see if there is 12v at the plugs during ignition.. but this argues what I said before, that the glows are not used on an HDi when the temp is 5 - 10C

the messages about heater relays faukts etc on the first set of screenshots,, do they mean something after all,,
all errors cleared now but have not rechecked after driving today


ahhhrgggg

I think they DO use heaters but Ive been a belever they dont. Im led to think they are quick operate, not like the old XUD plugs that take ages...

HDi 8v plugs arent that bad to do, Ive not had an issue. Its the 16v 1.6 plugs that are a pita.

She could be heater plug lazy..

ahh

so, 8 valve not likely to snap off in the head? I will get engine warm etc,,

and.. could be a fault with the operation of all plugs, (as much as it could be a fault with 2 or 3 of them as per TD days)

what would be useful, can anyone confirm their HDi 8v actuates the plugs on ignition, at this time of year?

[Mandrake]

John, you had fault codes relating to glow plugs not working in the original fault read out you did.

Did you get around to clearing the fault codes and checking them again after attempting to start the engine ?

See if you can do that and post the fault codes. Betcha there's at least one about the glow plugs

[jgra1]

hi Simon

today is the first day I have used car since clearing the codes yesterday I think ;P but yes will re read them in morning

[Chris570]

Easy start will help the engine spin faster which makes the pump turn faster which in turn may mask a weak pump / leaky injector. WFA had the same thing with a F*rd that would sometimes start au natural but when easy start was added it would start and idle and drive perfectly it was just at cranking the pump was too weak.

Heater plugs certainly don't aid that first firing as they simply don't have time as you can start a key with just turning the key.

Seriously my thoughts are injector 4 is the problem and it's sapping all of your pressure (much like Paul had)

[citroenxm]

Yes good points chris..

I never looked to closely at my injectors, and didnt think about the logics.

John, do you want me to send a set of working injectors, like I offered (Sorry if you replied previously) before to you to rey first before spending out??

[Chris570]

you might as well only send 2 as I bet you only had one go.

I'm looking to get a spare fuel system in for mine.

(now at 236k)

I believe the HDi should start without plugs - however, they heat up very quickly (like <1s at 'normal' temps) so by the time you've switched on and started cranking it they're hot. The light on mine goes out very quickly unless it's v cold! My thoughts mirror Chris's - you've either got a leaky injector or a weak pump - easy start boosts the cranking speed as it fires, pushing up the pressure and allowing it to start injection (or a blocked fuel filter - as it appears to be a Siemens system, filter blockage could be causing low HP pump suction side, and therefore low HP side). So, change the filter, if that's no good then do a leak off test. I'm unsure if the injector correction relates to a leak off, Paul's were all showing no correction, but one (or more) was still leaking - probably!! One of mine shows quite a high correction, but it starts OK. At the moment....
