SuspiciousPizza Posted 5 hours ago Share Posted 5 hours ago For SPFI models, the fuel pressure discharge from the fuel pump is 36-50 psi. After the regulator is 20-24 psi @ 700rpm. The regulator drops the high pressure from the pump to a usable pressure for the injector. So there is a high pressure side and a low pressure side, separated by the fuel pressure regulator on the throttle body. Could be an issue with the fuel lines or filters. But most likely the fuel pump is tired and out of spec. Link to comment Share on other sites More sharing options...
