Fuel Pressure Test
Special Tools RequiredÂ
- Fuel Pressure Gauge 07406-004000B
- Fuel Pressure Gauge Attachment Set 07AAJ-S6MA150
- Relieve the fuel pressure (see FUEL PRESSURE RELIEVINGÂ ).
- Disconnect the quick-connect fitting. Attach the fuel pressure gauge set and the fuel gauge.
- Reinstall the air cleaner (A) (see AIR CLEANER REMOVAL/INSTALLATION ).
- Install PGM-FI main relay 2.
- Start the engine, and let it idle.
- If the engine starts, go to step  7.
- If the engine does not start, go to step 6.
- Check to see if the fuel pump is running: Listen to the fuel filler port with the fuel fill cap removed. The fuel pump should run for 2 seconds when the ignition switch is first turned to ON (II).
- If the pump runs, go to step 7.
- If the pump does not run, do the fuel pump circuit troubleshooting (see FUEL PUMP CIRCUIT TROUBLESHOOTINGÂ ).
- Read the fuel pressure gauge. The pressure should be 260-310 kPa (2.7-3.2 kgf/cm2
, 38-46 psi).
- If the pressure is OK, the test is complete.
- If the pressure is out of specification, replace the fuel pressure regulator (see FUEL PRESSURE REGULATOR REPLACEMENTÂ ) and the fuel filter (see FUEL FILTER REPLACEMENTÂ ), then recheck the fuel pressure.
