has a compression test been done
couldnt be bothered to read 15 pages
at first this sounded like coil to me, but im wondering if it might be the head gasket, gone between cylinders
mine ran on 2 when that went, if you left the car for a while it would start again but run like crap

no they aint, problem on Mk1 Clio's as its under the scuttle panel and can get damp

Someone has suggested to me that the cambelt may have jumped a tooth? wouldnt this cause loss of compression too?
sounds like this guys problem too> http://www.cliosport.net/forum/showthread.php?t=147157&highlight=cambelt+jumped

No it doesn't affect compression.
It could of done mate but you said plugs temparaliy fixed it? Get it checked, it's not a big job to see if it has!

well after a chat with a friend of mine tonight he thinks its the cambelt and another mechanic freind of his thinks it is too.
Im going to phone about for someone to come and look at it tomo then take it to get replaced, maybe kenny brown or another knowledgeable place near by
anyone got a trailer?! lol

if the centre two cylinders are not sparking it can be down to just 1 wire... if the connection on the coilpack plug is not contacting properally it will cause this... i cant remember which one of the pins it is but its either the orange or the beige wire controls both the centre cylinder as they are wasted spark.... so both fire at the same time...
if it were belt issues there would be the same problem across all 4 i would have thought and as the compressions are good it seems its not mechanical at all.
indeed the belt was changed when the engine was built...
it seems to me this is a connector problem, trace the pin back from the coilpack to the pins of the ecu, pins 1a and 12a control the ignition on the omex 600 loom, so a simple continuity test will look at that..
then look at the pins in the plugs themselves, check that the connector has not been opened (say by probes put in there to test etc)... these can be removed from the plugs and bent back in so they contact properally on the pins of the coil and the ecu...
hope this helps

Is it smoking out the exhaust mate when its running on 2?? when cold mine would start but run on 3 and there would be white smoke pissing out the exhaust smelling of neat fuel. Tryed the coils, leads and spark plugs put my cat back on but it was still fooked. Any way plugged it into to my mates diagnostic tool and it said i had an injector fault. Two of my injectors were shagged and stuck wide open, fuel was being chucked in and putting out the spark so to speak. My clios on an 02 plate with 49,000 on the clock. Worth a poke mate.
That sounds like a possibility.
Swap the injectors round and see what happens. Is the car still on standard injectors?

I had the injector rail off last week too and let it spray while cranking, they pulsed in the correct order and a regular pattern across all 4.
It doesnt smoke at all, not even a little even if i give it a wee rev while its cold.
arrrgghhhhh its booked into Kenny Brown for next friday, f**king ages away

okay so towed the car to the garage, but thanks ali for the offer of the trailer.
The garage have come up with 2 possible options but trying the smallest first> the cambelt has slipped a notch or the ignition drivers are failing.
A question for the experts, does the omex take care of the ignition or the renault ecu?
GDI/omex are closed for the weekend, would like to know by monday if possible

the omex runs the ignition control, the power supply comes from the OE fuse box on the right side of the engine bay
the injectors are the same controlled by the omex, powered by the engine control relay.
I still feel that if the timing has slipped, it would not work on just 2 cylinders.

See both your points here, i dont think getting water near a electronics is a good idea full stop. But what i would like to know is why do you always feel the need to argue with people about GDI jesus? Like very company they have the good points and bad points. but for some reason you dont wanna accept that on the off chance they may have done something wrong. You make me laugh though lol

it is intermittant the running on 2, at least I should be able to knock out the fact its the omex to fault as it has been run on another car without failure.
Il speak to the garage on monday and see what he says, he may have checked the signal from the ecu to give him the idea thats whats causing it

Have you changed the leads? Arcing to the manifold maybe? I doubt the cambelt has slipped TBH. Hope t's sorted soon buddy, It's been a while!!

It has to be something in the ECU's then dude, I'm stumped!
Keep us posted mate.

okay an update as promised!
the car is fixed (sort of) It runs on 4 now but revs at 2k revs on idle. im think the VDO valve thingy, he maintains there is no air leaks on the inlet
the guy found a loose connection on the wiring loom, havent picked the car up yet so will reveal more when I know it.

Result! The idle thing does sound like an air leak but as he says there is'nt.... Have you tried blocking the carbon cannister pipe off? Mine split somewhere and would idle really high. I cut it and put a bung in the line and it was fine!
Map sensor leaking?

lol, I think il still be keeping it when its fixed, this car owes me
well its not fixed, not at all. Drove 200yds out the garage and it started again, he warned me it would but told me how to stop it and why he thinks it could be a lead (wouldnt show up on voltmeter) or possibly the omex hasnt been repaired.
Andy from GDI is very kindly is sending me up a spare set of leads to try.
If I cant sort it Andy has offered to fault find F.O.C. which means trailering allll the way down to him, could be the only option in the end.
