Engine Mechanical problem
2002 Renault Laguna 4 cyl Two Wheel Drive Manual
Car doesn't start when cold, but does when warm.
I've had glow plugs replaced, a new battery and a new crankshaft sensor.
If I take off the air filter and squirt WD-40 in the intake, it helps to start the engine.
The car idles and drives fine - No loss of power and is averaging low 50's in the mpg so appears fine here too.
Any ideas? Apparently the fuel is getting to the fuel rail ok. Does this sound like a problem with the pressure regulator or the injectors? Any help would be great.
