clio fuel cut off

[etaf]

i have a clio and it started to play up - when the weather is HOT the car often does not start - it turn over OK and then suddenly will start - also if you brake hard it stalls. Today it started first time - drove 1/2mile stopped to pop into newsagent and then would not start.
I checked all cables and everything for any mis-seated cables etc I then pushed hard on the fuel cut off and it started. The fuel cut off was not out - it did not click or anything - was this just coincidance do you think or is there a known problem on Clio's

Could be the cut off wasnt seated right......

it went wrong again yesterday - but started on 2nd turnover and this morning it worked OK .....
oh dear intermittent fault are expensive and painful

[deltaf]

Fuel pump relay possibly.

The fuel cut-offs on our Kangoo and Clio vans can be set off by simply mounting the kerb, may be a part actuation is also possible, took us two recoveries to realise this!

Thanks

was this intermittent and was the cutoff switch obviously out.
the car has worked fine all week so far - very frustrating as i have noidea when my wife will breakdown.
so apart from chaging the fuel pump/tcd/wiring/cuttoff i'm trying to isolate a common fault and go for that

We too had this problem when we bought our Clio a few weeks back. It had terrible problems starting, stalling etc, and we thought it was something to do with the fuel system. Took it to the dealers under warranty and it turned out to be the immoboliser on the keyfob!, Yep,, the keyfob wasn't programmed correctly, hence the car refusing to start (sometimes!!) and stuttery performance, (I use the term 'performance' in it's loosest possible sense, as it's a 60bhp 1.2 'monster' of an engine!!)
Technology eh!! lol

Thanks Chris,
the clio has a light down by the gear stick flashes when alarm set/unset.

did this show anything when it went wrong.

I think I maychange the batteries in the keys, they are getting towards 4 years old I usually replace every 2 years but just realised i havent done for 4years !!!!!!!! time flys by.

thansk for the reply

the cars been working all week - not a problem !!!

etaf,
I have to be honest, I never even knew there was a little red light for the alarm until you pointed it out to me!! (the other half drives it)
I think there is a little more to just changing the battery in the keyfob, you will need to get it done at a Renault dealer, as they also have to re programme the keyfob, so that it is in sync with the immobilliser (this was the reason we had probs with ours!)

Clio immobilisers are not affected by battery condition, early systems are un-immobilised when the doors are unlocked, later types, 1998 on, are operated via a transponder and need no battery in the fob. What model, age etc is yours? Have known a few problems with fuel cut off switches but easy to prove, disconnect and join the two wires together, they earth the fuel pump relay. These relays in later cars are a big problem, they absorb water like blotting paper.
Let me know what model it is and i`ll tell the common problems.

thanks Dave its and R reg 1997 Clio biaritz 1.2

These dont usually give too many problems but it should be easy enough to identify.
What happens to the immobiliser warning light when it wont start ?
When the immobiliser is set the light should flash slowly, switching on the ignition the light should go solid for a few seconds and then go off. If it starts flashing faster then it has not seen or recognised the key, normally with this model that points to the receiver ring mounted around the ignition switch, around £25 and 10 minutes to fit.

Hi, my partners car - i was not around
went wrong again on sunday - left it for 5 mins worked again.....
also went wrong today while my partner at work - light by the gearstick for the immobilser worked as normal. would not start for a large number of attempts everything OK except firing - i then arrived - so i done the same as worked last time - i pressed on the cut off switch hard - it was not up nor did it go click - turned car over no go. pushed it again turned over and fired - this is exactly what happened the last time i fixed it.......

just coincidance - i was going to change the switch anyway - but the renalt dealer near me could not find the part number and had promised to get back to me but what with one thing and another i didnt chase.

i tried to short it out with a bit of 2.5mm wiring cable but thats to thick for the holes....

perhaps i should just change that part and see

[my 350i]

The part no you need is
7700414373, price is £21.96 + vat, retail. How reasonable is that ?
Dave

[etaf]

Well its gone wrong twice now and each time if i push the top of that part it starts.
today i heard the fuel going through - so I ordered the part will arrive tomorrow - (non-refundable, as special order) however, i just thought is this just an electric reset switch and you only need to put pressure on it to work - so i'm actualy resetting another problem ???

how does this part work ????

[etaf]

i replaced the part on tuesday and its still playing up - anyway to imobilize the imobilizer - can i disable it in anyway.

[annodomini2]

On the diesels the immobiliser is in the ecu, don't know about the petrols, but if its the same, you'd have to reprogram the ecu with modified software to do it.

[my 350i]

The immobiliser is contained within the ecu on the petrol engines as well, unfortunately you cannot reprogramme easily as the whole thing is potted up in a rubber solution and it is not possible to remove the chip. Mail me offline and i may be able to help you out

i changed the key fob batteries and the car seems OK now

I have a 1997 (R) Renault Clio 1.2 RL Paris and I have had the same problems, although quite rate. I can honestly say that my engine normally cuts after heavy braking, and sometimes when you try to restart when it is hot. It did it down at Asda last week, look a right nutter in the car park trying to start it!

Not sure what year your Clio is, but on mine there is an injector warning light that illuminates before you start the engine (then you can hear a noise from the engine, fuel or injectors?). After you start the engine, the light should go out. Should also go out if you leave the ignition on. I used to just start the engine without waiting for this light to go out, but if your engine dosen't start, try waiting for the light to go out before trying to start and it should fire up straight away.

Are you supposed to wait for the injector warning light to go out before starting the engine anyway? Just so I can check, where is the fuel cut off switch under the bonnet? Looked all over, can't locate it.
