Fuel Pressure: Testing and Inspection

Fuel Pressure Test

Special Tools Required
Fuel pressure gauge 07406-004000B

1. Relieve the fuel pressure.




2. Remove the bolt (A). Attach the fuel pressure gauge with a new O-ring.
3. 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.

4. 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 on.

- If the pump runs, go to step 5.
- If the pump does not run, do the fuel pump circuit troubleshooting.

5. Read the fuel pressure gauge. The pressure should be 270 - 320 kPa (2.8 - 3.3 kgf/sq.cm, 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, then recheck the fuel pressure.
