What causes low fuel rail pressure in the EA888 engine?
1 Answers
Here are the reasons for low fuel rail pressure in the EA888 engine: 1. Fuel line blockage: Blockage in the fuel line or excessive water content in the fuel can lead to low rail pressure. 2. Fuel pipe damage: All cylinder injectors are connected to a common fuel pipe (referred to as the fuel rail), which maintains constant pressure. Damage to this rail can result in low pressure. 3. Injector blockage: If the fuel injectors are clogged or damaged, it can also cause low rail pressure. 4. Malfunction: Low fuel rail pressure is mainly caused by plunger wear, common rail pressure regulator failure, or ECU malfunction.
