Hi everyone, I am in South Africa, a good friend of mine owns a 807 2.2 diesel. It does not want to start, although when you initialy crank the engine it does seem to want to start then theres just nothing. I had the lexia on it.....crank speed 180rpm, fuel pressure round about 300bar, crank/cam synchronization= YES. However what strikes me as funny is that we have a permanent fault - crankshaft/camshaft synchronization - Camshaft sensor no signal, which comes up every time after cranking the engine? There is also post/pre heat relay stuck failure, which I do not think is stopping it from starting? Any ideas? I am unable to get to the cam sensor as on the 807 the engine is below the dash, leaning backwards, I cannot even see the sensor, nevermind get to it or its connector. I cannot figure how we would get cam/crank sync=yes if the cam sensor is not outputting signal as the fault code suggests?
