Fuel System
- Connect fuel pressure gauge to pressure relief valve on fuel rail assembly. See Figure . Pressurize fuel system by starting and running engine or turning ignition off and to "RUN" position several times. Fuel pressure should be 35-45 psi (2.5-3.0 kg/cm2 ).
- If pressure is not correct, check to ensure ignition coil is connected. Ensure that injectors, fuel pressure regulator or fuel delivery lines and connections are not leaking.
- If no pressure reading can be obtained, check fuel pump circuit. When fuel pressure is obtained, turn key off. Pressure must not drop more than 4 psi (.3 kg/cm2 ) within 2 minutes after ignition is turned off.
- If pressure drops more than specified, check for hydrostatic lock, leaking injector and/or faulty pressure regulator.
