While some fuel pressure regulators are built into the fuel pump assembly, most fuel pressure regulators are mounted in the fuel rail and can be serviced independently of the rest of the system.
Can a bad fuel pressure regulator cause a misfire?
There are also many causes of engine misfires. It can be a problem in the spark plug or the ignition coil. A fuel injector problem can also cause engine misfires. It is also one of the symptoms of a bad fuel pressure regulator. A problem with this device can lead to low fuel pressure.
Can a faulty fuel pressure regulator cause a car to not start?

How to test a fuel pressure regulator ( FPR )?
Testing for Maximum Pressure The easiest way to test an FPR is with the use of a fuel pressure gauge. But first, you’ll start your tests with a quick preliminary check: 1. Open the hood and locate the fuel pressure regulator on one end of the fuel rail. This rail holds the fuel injectors in place.
Can a fuel pressure regulator leak into the vacuum hose?
