I checked the fuel pressure today at idle it was 33 psi. When I shut off the engine the pressure went down to 5 psi in an hours.
i shut of the engine and unhooked the robber return line to the fuel tank of the fuel pressure regulator. It was not bleeding fuel however the pressure was going down.
what could be the problem fuel injectors or fuel pump and how can I check fuel injector if they leaks?
