Clio 182 cranking but not starting!

[mrc300]

I am a bit worried about the Clio at the moment
Here are the symptoms:


- Key in, wait for the lights to extinguish, try to start and it just cranks over.

- If I remove the key, close the door, lock and unlock and then try again the engine will start up straight away 90% of the time. When the Engine is idling and running it sounds and runs as you would expect.


- It cuts out randomly. This morning around a roundabout, no warning lamps nothing it just died. I went for the Hazard switch but it did nothing. Third attempt at restarting and the engine started and I continued to work.

- There are no trouble codes that I could recover.


Background

- Car has a factory alarm fitted

- The other weekend when using Cruise Control on the Motorway everytime I used the RH indicator it would turn Cruise Control off, possible related issue??



Any help at all would be greatly appreciated!

Crank position sensor probably.

Common fault

Try giving it a wiggle with someone cranking it over when its not starting, its located underneath the airbox.

Would this cause the car to cut out though with no warning lamp or codes?

 

[Carlv8415]

Yes! Had the fault on my 1.2. Would turn over but wouldn't start, once you got it started it would cut out randomly.

What should I clean the sensor with? It's worth a try.

Sounds like your UCH is playing up

Bit of petrol on a rag, give it a bit of a rub down.

electrical contact cleaner would be better

I have feared this, but I have not lost the function of any other electrical components. Lights, wipers, HEVAC all work its just the Hazard circuit, that obviously should work even without ignition. Would a faulty UCH cause the engine to cut out though?
This morning on the way to work it was very hesistant when driving out of my car park, I pulled over waited 2 minutes at idle then drove off. The car was fine for the rest of the journey.

Bit of a debate about how these cars react when cold. Mine runs badly initially for about a minute then settles out. That's what they suppose to do so I wouldn't worry about it...

Focus on the tdc sensor first before you start worrying about the uch.

I have owned the car for almost a year now, I'm fully aware how it runs on the cold map. This was something different.

Will do, I've noticed it doesn't start up only when it's left for a period (overnight) then following a key out, lock and unlock the car it will fire up first time.
