What Do You Mean By High-Pressure Fuel Pump?

Whether you are a BMW owner or a mini cooper owner, your vehicle always consists of two types of fuel pumps. The first one is known as an LPFP while the other is known as an HPFP. The LPFP is actually responsible for pulling fuel from your fuel tank.

On the other hand, the HPFP aims to move the fuel to the combustion chamber. In case your high-pressure fuel pump starts malfunctioning, you will not be able to drive it as you are accustomed. Once the malfunctioning is pointed out, you shouldn’t wait long to bring your vehicle to any expert manufacturer or mechanic.

What Are Malfunctioning Signs In BMW’s High-Pressure Fuel Pump?

  • One of the major signs Showing malfunctioning of your BMW is that it starts losing its power when it accelerates or goes uphill.
  • To detect malfunctioning, you can also make use of a fuel pressure gauge.
  • The second most important sign is that your vehicle is taking too much time to get started. This indicates that the high-pressure fuel pump is not doing well. This happens due to leakage in the high-pressure fuel pump.  The leakage in the fuel pump depressurizes the whole vehicle causing it to give you low performance. With the depressurized fuel pump, it may become harder to pull the fuel to the combustion chamber. This is how it starts malfunctioning.


In order to determine the malfunctioning of your high-pressure fuel pump, you should talk to an experienced and skilled mechanic. Doing everything on your own may result in more damage.
