Grand scenic hot starting issue

[steve j]

Can someone help me with a problem, I have a Renault grand scenic 1.5 dci that starts first time when cold. Once the engine warms up it refuses to start, it shows up "Injector fault" on the dash. I`m guessing that it`s the coolant temperature sensor as the problem is temperature related. I`ve had the camshaft position sensor out and cleaned it and the problem persists. Any help/advice gratefully recieved

Could be a failing injector you could try doing a leak down test when it's hot.Or fuel rail pressure sensor,i think from memory there is a sensor on the pump as well.
Will it start with a squirt of easy start when its hot?
