Can You Continue Driving If the High-Pressure Fuel Pump Is Broken?

[DiQuinn]

You can continue driving if the high-pressure fuel pump is damaged. Early symptoms of a failing high-pressure fuel pump may include weak acceleration, jerking during sudden acceleration, difficulty starting, illuminated engine warning light, and unstable idle. When the high-pressure fuel pump fails, it only needs to be replaced with a new one. It is recommended to use genuine parts and have the replacement done at a 4S shop. The high-pressure fuel pump, also known as the injection pump, is the most critical component in the fuel system. The requirements for the injection pump are as follows: 1. The fuel supply of the injection pump should meet the needs of the diesel engine under various operating conditions, i.e., supplying more fuel under heavy loads and less under light loads. At the same time, it must ensure equal fuel supply to each cylinder. 2. According to the requirements of the diesel engine, the injection pump must ensure that the fuel supply start time is the same for each cylinder. 3. Depending on the combustion chamber design and the method of mixture formation, the injection pump must provide fuel at sufficient pressure to the injector to ensure good atomization quality.
