燃油泵出现故障汽车会出现什么症状,该如何解决

02-06

汽油喷射系统中燃油泵是极其关键的部件,一旦燃油泵出现故障汽车就会出现各种不良的症状。下面我们来了解一下燃油泵出现故障会给汽车带来哪些问题。

燃油泵故障会引起汽车
引擎可以点火,但无法启动
燃料泵内部可能泄漏
过度的噪音
缺乏动力
加速时候卡顿无力

燃油泵相关的维修建议
大多数现代汽车电动燃油泵都是安装在油箱内。一些车辆访问面板看到燃油泵工作情况无需拆卸油箱就知道燃油泵好坏了。
油箱内的燃料泵要淹没在燃油里用来帮助燃料保持低温状态。如果燃油泵运行时暴露在空气中会很快损坏。
在更换燃油泵时燃油过滤器应该也更换新的
过滤器阻塞或电气系统驱动燃油泵问题可能导致症状类似于一个有故障的燃油泵。

汽油是高度易燃。维修店在确认是燃油的问题更换燃油泵之前电池应断开连接和做适当的安全程序,以避免火灾和人身伤害。

Symptoms of Wear or Failure

  • Engine will crank, but fail to start
  • Fuel pump may leak internally
  • Excessive noise
  • Lack of power
  • Hesitation when accelerating

Related Repair Advice

  • Most modern vehicles use an electric fuel pump, which is mounted inside the fuel tank. Some vehicles have an access panel that can be removed to replace the pump without having to remove the fuel tank.
  • In-tank fuel pumps are submerged in fuel to help keep them cool. Running out of gas can damage the fuel pump.
  • The fuel filter should always be replaced when replacing the fuel pump
  • A clogged fuel filter or problems with the electrical system powering the fuel pump can result in symptoms similar to a failed fuel pump. Have the shop verify that the pump is the problem before replacing.
  • Gasoline is highly flammable. When replacing the fuel pump, the battery should be disconnected and proper safety procedures followed to avoid fire and personal injury.
