Starting problem Clio RS 197

[Frederic]

Hello,
I have a Renault Clio RS 197 2006 with about 90 000km.
The car is used regularly but yesterday it unfortunately did not start.
It turns around on the starter but does not fire up. The battery is in good condition.
I have tried an OBD reader of a simple model for error code reading but there are no DTC stored.
I have on a couple of occasion driven the car with basically no gas in the fueltank. The question is whether it may have damaged the fuel pump. How do I check the operation of the fuel pump easiest?
Is there a lot of work to dismantle it?

I welcome any tips on what may be causing the starting problem.
Greetings from Sweden!

Can someone please tell me which of all the relays under the bonnet is the fuel pump relay?

The problem is now solved. A tip to those with similar problems. It was the camshaft sensor. It was basically covered in oil which probably interfered the signal.

The Cam sensor lives in the top of the engine/cam cover and so is supposed to get covered in oil. The car should also start without the Cam Position Sensor so I suspect you may see this issue again chap.

fuel pump would be my punt

I had one just die whilst driving, just cut out, had to get a tow home

Its a reasonably common issue and will also give your symptoms.

Hey folks,
@MicKPM That's very strange since the car started after cleaning of the camshaft sensor. Are you sure about that the car should start without the camshaft sensor connected? In my opinion it wont since it needs to know the position of the camshaft in order to be able to give the spark.
@Gaz_ The car works fine now. Do you think the fuelpump can stop working and then suddenly work again?

@Frederic no it doesn't, the Crank Sensor is the foundation signal for the ECU and the Cam Sensor is a supplemental signal from which the ECU can ascertain the position or "phase" of the camshaft relative to the piston position.
