Hello all,I have a 01 Golf and it won't start.The injection pump won't pump fuel.There is fuel to it.If you remove the top cover and turn the piece that moves the metering sleeve it will pump fuel.So that tells me the pump itself will work.I just need to know if there is any diagnostic info so I can determine if it is the accuator on the top of the pump or it isn't receiving the correct signal from the car.Any help or info would be greatly appreciated. Jim
