Why is fuel consumption higher after replacing the fuel pump?
1 Answers
Reasons for increased fuel consumption after replacing the fuel pump are as follows: The new pump core has higher fuel pressure, injecting more fuel in the same time period, while the ECU still follows the injection timing of the old pump core, resulting in slightly higher fuel consumption. This will normalize after the computer self-adjusts during driving. Additional information: Fuel consumption is related to driving habits. Start slowly; during vehicle acceleration, use low gear and gently press the accelerator to gradually increase speed. Avoid sudden hard acceleration, as this can multiply fuel consumption. Gentle acceleration not only shortens engine warm-up time but also improves fuel efficiency, achieving better fuel economy.
