Citroen Relay - Having problem starting

I am having trouble starting my 2.2 hdi relay 03 reg. I initially broke down with the fuel inertia switch tripping out. Then after a computer check on the engine management system, I had the fuel rail pressure sensor changed as it was showing as working intermitently. Then after still having problems startin, my mechanic testing the batt and alternator and I have now replaced the alternator as it was showing as not working properly.
Now I am still having the same problem. It just turns over but does not kick in. This then wears the batt down and I either have to charge the batt or jump. Jumping the van is in fact the only way it will start at the mo, and that still took about 5 mins last night.
Is it fuel related, I think so, but I don't know.?
Can anyone help as it is costing a shed load of money and it is off the road at the mo, wanting to be used.?

had a diagnoistic test been done and any fault codes? if none then i would be looking at fuel system, pipes for fuel drain back, and get the injectors checked by doing a leak off check. make sure the immobiliser is not on, any light flashing? have you tried the spare key if it is? problems like yours need proper diagnostics, and reading live data to see if you have good fuel pressure and crank sensor signals. fitting new part in the hope of fixing it is not the way forward, there may well be a problem withe the parts fitted but clearly its not fixed your problems. and your wallet is been hit hard by the sound of it!

A test was done a few weeks ago, which brought up the fuel rail pressure sensor as not working properly. I have spoken to another mechanic since and he has mentioned checking the injectors as well. So I think this is the next step.
I totally agree that I'm not going to have any new parts fitted now unless necessary. And your right again it has hit my wallet hard.
Cheers Bigtony..

hi matt. yes very true. i work in the trade and see problems like yours day to day. other garages just fitting parts unecessary. The garage im at is a honest one.and we always try to diagnose the problems the best we can and let the customer decide on if they want the work doing or not.
Right your fuel pressure sensor had come faulty, may cause a non start fault , but i would think it would start but be in limp home mode, unless its really kaput. but the ecu should use a default value so you can still drive it. can you get the garage to give you an exact description of the fault code? ie circuit failure, low pressure, get a fault code number.. really like i said if they can get it so its not starting and look at live data and that will gove them a idea of whats wrong, If an injector is faulty, it will not let the common rail system build up the minimum pressure to start.

I forgot to mention in the first message that I have had all the glowplugs changed, 3 of them being done ok and the last one had to be drilled out as stuck fast.. I will try to find out what the codes were..

Im pretty certain this aint a glow plug issue fasty. like i said these common rails dont need glow plugs to fire up unless minus degrees to aid start and cold running,

np m8. yeah its really bad here too. bout minus 4 at mo.. need good working glow plugs in this weather! i was just thinking too. ford tdci common rails use glow plugs quite a bit to improve cold running i have been told, most modern diesels dont really need them so much. must be the design of it.

All I could find out code wise, was it came up.. Fuel Rail Pressure Low, Pressure Switch Failure..

I have just got hold of my mechanic, and he had found a company that will clean and test each fuel injector for £25 each. Does that sound like a reasonable price? I really dont want to spend more than i need to!

.. hi matt. hmm what exactly have they done? the injectors dont need taking out and testing yet. as that would be a waste of more money. have they carried out a injector leak off test to see if there is an injector leaking back excessively into the return. this would cause a loss of fuel pressure , very bad starting.They will need a proper kit to test the injector for leak off., if you have low pressure you will get a fuel pressure sensor fault. also make sure the fuel pipes are ok, small split can get air into the system and also cause similar problems.is the fuel filter ok too?

Hi matt, just wanna stress that im only offering my profesional opinion on this matter, and you dont have to follow exactly what i say. I just hope to help you sort your problem out without you spending money on it in areas which you dont need too. If all the injectors are taken out and tested, they may well find a problem with them and rectify it but its not 100% that the injectors are the cause, A leak off check is a quickest way to check the injectors for fault without removing them from the engine.Most decent garages will have a kit to test and know how to do it.Or find a diesel specialist. A good one we use at work is a company called feather diesel, you can find them online. brillient company, they really know their stuff! you can always ask them for advise too.
Ive had a fair bit to do with diesels, more the later common rail stuff, they are pretty advanced and you really have to understand how they work to be able to fix them, But honestly there are guys out there are really know there stuff on these, and what ive told you is pretty basic! :)
Let me know how you get on. Im up in the north region of uk, feel free to pm me if you wish.

Hi there as you say the engine starts with help from another battery. have you actually checked to see if the pre heaters are getting power them from the pre heater relay.

Hi there, if you mean glow plugs when you say pre heaters then they should be ok, only a couple of months old..

The problem hopefully cross fingers... has been fixed for the mo, I had my fuel filter cleaned out and other fuel pipes checked, then I added some injector cleaner to the fuel. It was ok for a few days then the same problem. But I reckon the gunk prob blocked up the filter again so I had the fuel filter changed and it seems ok ...
We will see...
Cheers Matt.

Hi Matt, yes i do mean the glow plugs, regardless whether they are only 6 months old if they are not getting hot because they are not getting any voltage to them from the control relay, at this temprature, even the hdi engine is going to struggle starting. it will take about 5 minutes cranking to raise the cylinder temp enough to fire the fuel.
will it start and continue to run if you put any eyther on the air filter element or spray eastystart into the air filter box.

hi there, that is something I could get checked out cheers.
At the mo it is starting alright, just had one day last week sometime when it took about 10-15 secs to start, but while it is starting ok I will just hold tight and keep my fingers crossed.
With regards to the cold start srpay, I did try that a couple of times when it wasn't starting and yes it worked fine, but have not used it anymore as I heard if you use it regulary your engine can become addicted to it.

if its starting ok now the air temp has come up a bit, and it started ok with easystart, i would definatly be looking at the heater plug control relay.
