1.2 8V (D7F) Won't Start

[Gaz.]

Soph's clio won't start. Fuel Pump is priming. Had the AA out, and he said the coil pack had no output. So we've replaced that, still won't fire up.

He tested the crank sensor and that was giving an output.

Any Ideas?

Is it turning over? Immobiliser light going out as it should?

 

[Da]

As above, what's it doing?

 

[mklee86]

could be starter motor connections if not cranking over?????

 

[Gaz.]

It turns over. Immobiliser light now comes on solid when ignition turned on, then goes off. It has stayed flashing before apparently. However, I believe the unknown aftermarket alarm also immobilises the engine, which seems to be working as normal.

 

[Gaz.]

Soph's dad has tried cleaning countless sensor connections etc. Still no luck.

Sounds like a key problem if the light is flashing.

Neither key starts the car.

How olds the battery in the car?

Couldn't say TBH. It's not flat though as all the lights etc come on, and it physically cranks the engine over. Just no ignition being produced.

 

[Beef-Mc]

Mine was the same though, all lights, radio etc would work, but on trying to start it, the immobiliser would kick in (solid red light) and would refuse to start, changed over the battery and all was good.

Worth a shot. However, just found one key doesn't even have a battery in! No wonder that one did nothing.

Tap the starter motor while turning the key? Mines just had a new starter motor put in.

Starter turns dude.

try cleaning all the earths on the engine and gearbox

 

[mini-valver]

Its cranking so it isn't the starter.

If the light is going out after a few seconds then the immobilisor is fine too. If not, Try unlocking and locking the doors a few times, putting the key in and turning the ignition on and off a few times. Pull the key out, lock/unlock the doors, then try it.

Wouldn't crank if you have bad earths.

Try a bew battery

without soudning silly, have you tried the fuel cut off switch under the bonnet to make sure its not depressed. My little sister has a 1.2 8v, she went over a pot hole and then the car shortly after cut out and wouldnt start. The fuel cut off switch has gone in.

 

[Gaz.]

Her dad cleaned up a load of connections yesterday with no luck. Gone out to it a few minutes ago, and it's fired up. But the problem wasn't solved after all he did yesterday, so it's still technically speaking not sorted.

 

[Nickharding]

Either a new battery of a timing sensor, one went on my mums megan, theres a mark on the fly wheel and when it passes the sensor it tells it to do its thing, if this dont work, it wont give a spark, pull one of the leads off and hold it a few mm away from a metal object on the engine, and get someone to turn it over, if you see a spark jumping back and forth, its not the sensor, if it is, get a new sensor, its a common fault with renaults. Just make sure your hand aint near the end of the lead as it will give you a nipping shock!!

 

[BioHzrd]

replace the battery in the key ?

 

[Gaz.]

Oh and now it's started itself. Tried the old coil pack and that thing works too. FFS lol.

 

[Nickharding]

Yeh, the megan used to do that, if you start finding its intermitant, replace the timing sensor, its a comon fault - Cheap as chips too.

 

[Gaz.]

Fair enough.

 

[A18XHO]

What caused it to not start in the first place? have you pressed that red button by the battery??

 

[Gaz.]

Nope. She drove it, parked up, came back to it and it wouldn't start.

 

[Gaz.]

Just received the following information;

Alarm says Low Key Fob Battery. Bonnet & Boot sensor set alarm off so I think it immobilised it. Going to get some new batteries for the key fobs.

 

[Nickharding]

Tidy

Iv got the crappy 1.2 8v D7F aswell and i had starting problems too. Would start sometimes but other times it wouldnt. I replaced the TDC sensor ( second time the car has had one ) and iv not had a problem since

 

[Gaz.]

It's been out and cleaned. If the key fob batteries don't solve it then will try the sensor. Can't get one today anyway.

 

[Dm_26]

I took mine out to start with and cleaned it and it did work, but after about a week it started going wrong again so i just replaced it

 

[Sean6545]

Key fob batteries will do nothing. Take it to a garage and stop replacing stuff!

Like i said, common Fault

All we've replaced is a few measly batteries and a coil pack. It's running for the time being. How much would Renault charge her to fix the thing, a bloody fortune I bet.

 

[blackmagic]

also, has any one else having trouble with there imobilisers as some door bells interfere with the signal from car remotes try towing it dwn the road and try hopefully it will start mate,
