Fuel pressure regulators are common failures on LLY trucks. If you have a scan tool capable of viewing desired rail pressure and actual rail pressure, you'll likely see these numbers have a large spread on trucks trying to overcome FPR issues at idle. Keep in mind, a FPR failure may indicate your fuel system has been contaminated. Its best practice to replace your fuel filter during service.
