I have a renault diesel dci clio. It just will not start without

Customer Question

I have a renault diesel dci clio.
It just will not start without easy start unless its been running for about 30 minutes.
It runs ok and is still doing 75 mpg.
However if i accelerate hard in a high gear the engine warning light comes up.
If i accelerate moderately all is fine right upto top speed.
There are no hesitations.
I hooked upto a diagnostic unit and it came up with 2 faults.
The camshaft sensor and the fuel pressure regulator.
I swapped these with known good ones but the engine still wont start easily.
Im at a loss now where to look.
I have correct voltage at the connector plugs and no sign of any wiring damage.
Any ideas ?

Hello.

Mark :

Can you tell me what variant of the K9K engine you have. ie 700, 702 etc.

Mark :

Some of these vehicles are known to have this type of fault and it is mainly due to a faulty crankshaft sensor.

JACUSTOMER-wvetegao- :

I have replaced the camshaft sensor.

JACUSTOMER-wvetegao- :

Just removed crankshaft sensor and cleaned it up.....no difference will have to try a new one i suppose..

Mark :

That would be best and they aren't that expensive.
