Abstracts: In the present time, the whole transportation system is depending on diesel automobiles, where the operating cost of is very high and it also losses it’s performance after certain period. One of the reasons of this is degradation in fuel injection system which runs at high pressure and temperature and it also handle fuel of various qualities which results in reduction in performance of those parts and increase maintenance cost after long run. To operate diesel automobile with minimum running cost and maintain its performance, fuel injection system needed to be maintained which mainly consist of fuel pump, fuel injector and fuel nozzle. A repairing cost of system may be reduced by reusing parts like fuel injector, fuel nozzle, fuel pump after testing and maintain performance with the help of pump calibration device, injector & nozzle testing machine, injector code generation rather than replace it by new component. This project is carried out at Desai Diesel and Auto Service Center at Surat-Udhna. Numbers of readings are taken with the help of nozzle and injector testing machine, pump calibration machine and nozzle testing machine. Improvements in the fuel injection systems of internal combustion engines can also substantially reduce the emission of harmful pollutants
