C5 Won't Start

[bigmick]

Hi everybody, been a member for a long time but never posted before.

 

Had My 2002 C5 2L HDI Turbo 110 for 3 years, never had any problems till now.

 

Went to start car this morning, and it won't start. It has been running fine no problems, the engine

is turning over, but won't start, no display showing on dash at all, have checked fuses and all seem

to be fine.

 

Can anybody help, with some information.

 

Thanks Bigmick

no dash lights at all ? could be immobilizer not recognising the chip in the key they have been known to be wiped if remote is operated out of range, not a lot to go on with this as fault codes needed

Any fault codes or not. Mind it has been cold today and no doubt quite a few cars will have had to use there heater systems to get started only to find that the system that hasnt been used for quite a while now dosnt work. If its been fine then wont wont start on a very cold day then you need to start checking your heater plugs/relays/wires etc etc. A diagnostic should show this up straight away in the meantime give it a tow and it should fire up then itl probally fire up fine for the rest of the day

Did you have any display when you keyed on, and before cranking? And how did it sound when cranking, was it very slow, or about same as normal?

I would turn the ignition on, and wait for the warning lights to go out, count to 5, then I would turn off again, without turning the engine over, and I would do it several times.

 

This might get the plugs to fire up but from memory they only preheat below -5 C.

 

When you've done this several times then try and start.

 

Long shot but worth trying. Best with IDI engines, not DI.

There was no display when i first turned key, I was surprised that it was turning over at all, in fact it was cranking as normal.

 

A few weeks ago something similar happened, the display was all well, it was turning over

but not starting. This was pinned down to the ECU fuse, checked this first, this time.

 

Thanks

no lights on the dash when ignition turned on is the one thing that concerns me and its reminds me of the infamous Audi problem and that's the ignition barrel black box on the rear of the barrel, because its plastic it cracks and things start going strange because of it and your problem is the same and the repair is to replace the black box after an inspection of course

 

 

this is for the Audi but the principle is the same

I would agree with techbod, ignition switch is worth checking. Recently had one do a very similar thing on a Micra. A little concerned about the ECU fuse popping, if it goes again I would investigate further..

 

Let us know the outcome please.

Got display working again, loose connector at fuse box.

But still no joy with starting, mechanic coming in the morning to put diagnostics on,

let you know how we go on.

hmmm getting the dash lights to work is a good start now as to why that happened will be a mystery but because it happened it could have triggered a short out and popped up the fuel shut off solenoid which would allow the engine to crank but no fuel so it might be a simple push of that button ( hopefully it will be that simple ) good luck ;)

Glow plugs operate as follows when ignition keyed on and before crank:

 

0C on for 0.5 of a second

-10C on for 5 seconds

-30C on for 20 seconds

 

If you do not crank when the glowlight goes out, glows will continue for a maximum of 10 seconds.

 

During cranking, glow plugs will only operate if:

 

Coolant temp is below 20C

Engine is cranking at => 70RPM for 0.2 seconds.

 

Glow plugs will continue after engine start for 60 seconds maximum, but will be turned off if:

 

Coolants temp rises above 20C

Injectors delivering >35mm3

Engine RPM exceeds 2000

 

Hope that may be of use to someone..

Thanks Everybody,

problem was pinned down to a set of faulty glow plugs that were fitted two months ago,

must have been a bad batch. New set of Bosch plugs fitted, and away we go. :D

 

Thanks.

Good news, thanks for letting us know! :D

yep feed back is important to others and myself im glad you sorted it :unsure:

[myglaren]

What were the glowplugs previously fitted?

Beru are the recommended plugs but it is useful to know what the dud ones were (to avoid them). This is not an isolated incident, it comes up fairly frequently (not just Citroen of course)
