Fuel Pressure Test
Special Tools Required
- Fuel pressure gauge 07406-004000A
- Fuel pressure gauge attachment set 07AAJ-S6MA150
- Relieve the fuel pressure (see FUEL PRESSURE RELIEVING ).
- Disconnect the quick-connect fitting (A). Attach the fuel pressure gauge set and the fuel pressure gauge.
- Start the engine, and let it idle.
- If the engine starts, go to step 5.
- If the engine does not start, go to step 4.
- Check to see if the fuel pump is running: listen to the fuel fill port with the fuel cap removed. The fuel pump should run for 2 seconds when the ignition switch is first turned on.
- If the pump runs, go to step 5.
- If the pump does not run, do the fuel pump circuit troubleshooting (see FUEL PUMP CIRCUIT TROUBLESHOOTING ).
- Read the pressure gauge. The pressure should be 390-440 kPa (4.0-4.5 kg/cm2, 57-64 psi).
- If the pressure is OK and the engine is running, the test is complete. If the engine is not running, repair the cause, then continue this test.
- If the pressure is out of specification and the fuel lines are OK, replace the pressure regulator (see FUEL PRESSURE REGULATOR REPLACEMENT ).
