What causes stiction of the spool valve on a diesel?

Where is the low pressure pump on a diesel engine?
Not all vehicles have a low pressure supply pump but if they do, it can be found either in the tank or on the fuel line near the tank. If your low pressure pump is faulty, you may experience symptoms similar to those of a faulty high pressure pump. With low fuel pressure to the injection pump, the engine will ‘starve’ for fuel.
How can you tell if a diesel engine is bad?
Generally a diagnosis as to what’s wrong with a diesel engine can be identified by the colour of smoke coming from the exhaust pipe. There are three basic colours – ‘Black’, ‘White’ and ‘Blue’. This is normally caused by the fuel being injected and not burning correctly.
