What are the symptoms of excessive fuel pressure?
2 Answers
Excessive fuel pump pressure can disrupt normal lubrication conditions. Factors such as excessive oil viscosity, deterioration and gumming, clogged filters and oil passages, or improperly adjusted or stuck pressure relief valves can all lead to excessively high oil pressure. Below are relevant details: 1. Fuel Pump: The fuel pump is a crucial component of the automobile's fuel supply system. If it fails to operate while driving, it can directly prevent the vehicle from moving. Poor performance may result in sluggish acceleration. Failures often occur without warning, making the vehicle unable to start, which is inconvenient to handle. Therefore, timely detection, diagnosis, and resolution of issues are essential. 2. Hazards: Fuel serves to cool and lubricate the fuel pump. Ignoring low fuel warnings reduces the cooling and lubrication effects, leading to damage. Impurities in low-quality fuel can clog the fuel supply system and cause wear and damage to the pump. Early fuel pump failures are often caused by the use of substandard fuel.
I've been driving for over a decade and have encountered high fuel pressure issues several times. When the car starts, the engine shakes violently at idle, as if vibrating. During acceleration, it feels particularly weak, with delayed throttle response, making the car seem powerless. Fuel consumption also increases noticeably - what used to be 500 km per tank now might only reach 400 km. The exhaust emits a pungent smell and sometimes black smoke. Within a few days, the check engine light on the dashboard comes on, which is really annoying. It's best to go to a repair shop immediately to check the pressure regulator or sensors. Otherwise, prolonged operation like this can damage fuel injectors or cause more serious failures. In short, don't delay when you notice these symptoms - safety first.
