Renault clio starting problem
Sometimes the engine will not even turn - all the lights are on but the start motor does not activate. Seems to be totally intermittent - all I do is keep trying the key in the lock, rocking the car or walking away for a few minutes and then it works.
Could be a sensor, or the igition lock or anything?? But which sensor?
Or could it be the key fob?
I've checked the battery connections and they are ok.
Anyone got any ideas? Because it is intermittent its difficult to diagnose.

The most common cause would be the thin wire that goes onto the starter motor solenoid. there should only be 2, 1 thick red wire from battery. 1 thin wire which activates the solenoid. normally this thin wire comes loose or just doesn't make a good connection. next time it doesnt turn over try wiggling this wire & see if it starts.
If it is turning over but not starting,assuming its a petrol engine the most common cause would be a poor connection on the crankshaft sensor. this can be found ontop of the gearbox very close to the engine. it has a metal bar running accross with a bolt at each end.the sensor is the black part in the middle with a plug attached to it. wiggle the plug to start with it should then start. if it does ideally the plug needs to be disconnected & sprayed with switch cleaner...
hope this makes helps, good luck...
When we turn the key, all the lights come on, but the starter motor does not activate. It almost seem like the electronics is not allowing the start sequence to continue.
Could it be the ECU? - someone has suggested it can be a problem.
Any advice would be welcome.
Thanks for the reply, but I found the Forum about a month ago - I got some responses but then it stopped.
Here's another one I've used:
Recently changed the key fob battery and seems to be better (I hope!!)
nearly 2 years ago i added another battery earth lead to the gearbox bellhousing to run with the original renault one bolted to the inner wing,cleaned both battery terminals and iv never had another problem.I hope this helps someone and i recommend anyone to fit one anyway as the original even looks inadequate!!
