INSTALLATION PROCEDURETOOLS REQUIRED
- J 34730-1AFuel Pressure Gauge
- J 41041Fuel Pressure Gauge Adapter
1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief Procedure.
2. Disconnect the negative battery cable.
CAUTION: Refer to Battery Disconnect Caution in Service Precautions.
3. Remove the fuel plug bolt (1) from the end of the fuel rail.
4. Install the J 41041 to fuel rail.

9. Check for any fuel leaks and repair as necessary.
10. Start the engine.
11. Idle the engine at the normal operating temperature.
12. Verify the fuel pressure as follows:
- 210-260 kPa (30-37 psi) with the engine idling.
- 250-300 kPa (36-43 psi) when the engine is not running, the ignition switch is On, and the fuel pump running.
- The fuel pressure should hold at or more than 180 kPa (26 psi) within 1 minute of the engine not running while the ignition switch is Off and the fuel pump is not running.
13. If the fuel pressure is not within the specifications, refer to Fuel System Diagnosis.
