Reasons for Low Fuel Rail System Pressure?
1 Answers
Here are the reasons for low fuel rail system pressure: 1. Fuel line blockage: If the fuel line is clogged or there is too much water in the fuel, it will cause low fuel rail pressure. 2. Fuel injector leakage: All cylinder injectors are connected to a common fuel pipe (referred to as the fuel rail), which maintains constant pressure. If damaged, it will cause low fuel rail pressure. 3. Fuel injection pump blockage or damage: The high-pressure fuel injection pump delivers fuel to the fuel rail, which then sends it to the injectors. Each injector is connected to the common fuel rail via its own high-pressure fuel line. If blocked or damaged, it will cause low pressure.
