High Pressure Diesel Fuel Injection Pump 0 460 426 273 Engine Elements 0460426273

With the continuous development of automotive electronically controlled engine fuel injection technology, electronically controlled engines are comprehensively applied to modern automobiles, maintenance technology requirements continue to improve, in the field of automotive maintenance, the professional skills of maintenance technicians also have higher requirements, the field of automotive maintenance from mechanical repair gradually turned to electrical repair, and automotive oil pump circuit failure leads to one of the main reasons why the engine can not start, therefore, maintenance technicians should be able to Quickly master the automotive fuel pump circuit failure repair.

In automotive fault repair, the engine can not start is a common fault, caused by the engine can not start a lot of factors, the oil pump circuit failure is one of the main reasons for the engine can not start, the oil pump circuit failure repair is also an important part of the teaching of automotive repair, in the teaching, through the case of the introduction of the method of analysing the oil pump circuit failure caused by the electronic control of the engine can not start the reason.

When the engine won't start fault can be diagnosed and troubleshooting it in the following ways. (1) fault phenomenon: in the process of driving the engine off, the driver immediately and quickly start, the vehicle can not land signs. (2) analyse the possible causes of the failure. Including poor spark plug ignition, throttle blockage, oil circuit failure, sensor failure. (3) Troubleshooting and elimination methods. First, the maintenance of the vehicle appearance of the routine inspection, check the gear meter display is normal, no fault lights lit, start the engine, listen to the starter motor running strong, but can not catch the car. Second, exclude the battery and starting system problems, check the ignition system, remove the parting line and spark plugs, check the spark plugs without wetting, check the spark plugs jumping fire, spark plugs work normally, exclude the problem of spark plugs. Third, suspected fuel pump failure, remove the rear seat, did not hear the sound of fuel pump operation, judge the fuel line failure. Fourth, check the fuel pump insurance. Fifth, check the repair manual, find the fuel pump circuit diagram. (4) Troubleshooting: after troubleshooting, after loading the vehicle and test drive, the vehicle starts normally.
