What is a Fuel Pressure Regulator?

First, we will start with the basics. What exactly is a fuel pressure regulator? This essential engine management component is featured in nearly all internal combustion engines. What does it do? The fuel pressure regulator ensures that all gas that goes through the system is at the optimal pressure for that particular make and model. When the fuel pressure regulator is doing its job correctly, it also ensures that your engine is operating as the manufacturer intended.  However, when you are out and about in Waukegan or Libertyville, you may experience fuel pressure regulator symptoms that indicate something is wrong. Below, you will find a few of the most common symptoms of a bad fuel pressure regulator. 

 

Signs and Symptoms of a Bad Fuel Pressure Regulator

Your fuel pressure regulator could experience problems when there is too much pressure or not enough pressure. If this is the case, you may see the following fuel pressure regulator symptoms. 

  • You see smoke coming out of your vehicle – If you see black smoke coming out of the exhaust of your VW vehicle, especially when you start the car, it could be due to a faulty fuel pressure regulator. Rich engine running may also occur, which is when oil starts to come out of the engine. 
  • You notice noise coming from the fuel pump – A faulty fuel pressure regulator can also cause your vehicle to make a strange loud noise that typically comes from the fuel pump. 
  • Your vehicle stalls and sputters – When your vehicle is running on Vernon Hills roads, it could start sputtering if the fuel pressure regulator is not operating as it should. You may also experience your vehicle stalling soon after you start the engine. It is even possible that the engine will not start at all due to a bad fuel pressure regulator.
