Fuel System Rest Pressure
- Relieve fuel system pressure. See FUEL SYSTEM PRESSURE RELEASE under FUEL PRESSURE
. Connect a 0-100 psi (0-7.0 kg/cm2
) fuel pressure gauge to the pressure test port fitting on fuel rail. Start engine and note reading on pressure gauge. Shut engine off.
- Wait 30 minutes and check fuel pressure. Fuel pressure should be within 20 psi (1.4 kg/cm2
) of first reading. If pressure is not as indicated, check fuel system for leaks at fuel pressure regulator, fuel pump check valve or fuel injectors.
