Fuel Pressure: Testing and Inspection
1. Relieve fuel pressure. See Fuel Pressure Release.
2. Remove the service bolt and attach the fuel pressure gauge.
3. Start the engine. Measure the fuel pressure with the engine idling and the vacuum hose of the pressure regulator disconnected. Pressure should be:
235-275 kPa (2.35-2.75 kg/cm2, 33-39 psi)
4. If the fuel pressure is not as specified, first check the fuel pump. If the pump is OK, check the following:
If the pressure is higher than specified, inspect for:
^ Pinched or clogged fuel return hose or piping.
^ Faulty pressure regulator.
If the pressure is lower than specified, inspect for:
^ Clogged fuel filter.
^ Pinched or clogged fuel hose from the fuel tank to the fuel pump.
^ Pressure regulator failure.
^ Leakage in the fuel line.
^ Pinched, broken or disconnected regulator vacuum hose.
