My golf vr6 has been refusing to start for weeks cranking fine just not starting and no smell of fuel.i stuck a bit more petrol in it incase my gage was wrong,nothing then swapped over the fuel pump relay for a known working one still nothing so was resigned to the fact it was probably the fuel pump or maybe crankshaft sensor.Got in it tonight turned the key and it started straight away altho a bit rough on idle took it for a spin and now seems spot on again. Dont know if this helps but recently replaced the hall sender think someone mentioned the crankshaft sensor can go soon afterwards but n
