How to determine what broke down gasoline pump

How to determine what broke down gasoline pump, and as a result of any damage, interruption of his work? Sure - it's exogenous and endogenous damage. Endogenous damage associated with the cessation of operation of roller and gear elements gidronagnetatelya. Loud sound in the fuel pump, reducing engine power - is the result of exogenous damage. Termination of the engine (the car "sneezes"), violation of the fuel pump is due to damage to the impeller. If the motor sneezes while trying to launch, will not start, or a plant for a couple of seconds when you press the gas the engine stalls, then this is the first recognition of the wear of the collector node or working surfaces of the pump. Consequence of the termination of rotation of the armature after the power is podpalennaya slat. Run the anchor back into operation can be achieved by rocking the car in the trunk. As a result of such operations, fuel pump re-ignites. Between motor shaft and gidronagnetatelem is plastic sleeve, which in some cases subjected to destruction. Engineers - planners do not recommend to go with a flashing red light indicating that an empty gas tank, especially on hot days. The fact that the elements on which the fixed brush and begin to melt, and the brush no longer reach the collector. Gasoline pump may break in the case when the tank is filled to systematically defective gasoline mixed with solids. The presence of abrasive particles in the fuel, clogging the main filter input, notify the amplified sound of the fuel pump. By itself, scored the main filter is making a sound, but forces the fuel pump to operate with a vengeance. In this case, the cause of failure is overloading gasoline pump. Petrol pumps do not like water in gasoline - in the winter icicles formed scratch the work surface, and in summer - is reduced density of gasoline, and hence, its lubricating properties. Overheating of fuel pump contribute to short-term, systematic and recurring violations of contacts. One reason for the fuel pump failure is to stop the engine after a dramatic car hit a deep pothole on the highway. This provokes the inclusion of emergency inertia switch, which serves meals to the gasoline pump. Activities violate the fuel pump malfunction of ventilation gas tank and fuel vapor recovery system. If no contact is between the fuel tank and the air, then vacuum formed in the fuel tank, preventing petrol pump to collect petrol. Malfunctioning fuel pump lie in the fact that the first car moves quite smoothly, but after 50 miles, it suddenly "sneezes", there is a gradual reduction in engine power. After a brief "rest" car, the engine re-starts, and the car runs the same distance. When uncork the filler tank, about the problems with the gasoline pump notifies the drawing loud air in the fuel tank. To get there without any incidents until the first service station, did not recommend the filler tank to the end of spinning. All of the above causes of failure of fuel pump, the following conclusions: it is important to monitor the quality of petrol used, the purity of the fuel tank, do not be lazy to change the fuel filters, take a rule, ride filled with at least half a tank, avoid contact with moisture in the gasoline pump, do not expose it to mechanical stress.
