Relieve the fuel pressure (see 2004-2005 MODELS ).
Remove the 6 mm service bolt from the fuel rail. Attach the fuel pressure gauge (A).

Remove the vacuum hose (B) from the fuel pulsation damper (C), and pinch off the hose with a clamp (D).
Start the engine, and let it idle.
- If the engine starts, go to step 6 .
- If the engine does not start, go to step 5.
Check to see if the fuel pump is running: listen to the fuel fill port with the fuel fill cap removed. The fuel pump should run for 2 seconds when the ignition switch is first turned ON (II).
- If the fuel pump runs, go to step 6.
- If the fuel pump does not run, perform the fuel pump circuit troubleshooting; 2004 model (see 2000-2004 MODELS ), 2005 model (see 2005-2006 MODELS ).
Read the pressure gauge. The pressure should be 270-320 kPa (2.8-3.3 kgf/cm² , 40-47 psi).
- If the pressure is OK, the test is complete.
- If the pressure is out of specification, replace the fuel pressure regulator and the fuel filter (see FUEL PRESSURE REGULATOR REPLACEMENT ), and recheck the fuel pressure.
Reconnect the vacuum hose, remove the pressure gauge, and reinstall the sealing nut with a new washer. Tighten the sealing nut to 22 N.m (2.2 kgf.m, 16 lbf.ft).
NOTE: Disassemble and clean the fuel pressure gauge attachment thoroughly after use.
