Installation Procedure
NOTE:
Applying force to the plastic housing of the sensor will destroy the sensor. To tighten or loosen, only apply force to the attached hexagon.
NOTE:
Ensure that the fuel rail threads have been cleaned of any excess fuel, or the NEW fuel injection fuel rail fuel pressure sensor will NOT seal properly.
- Lubricate the threads and the sealing cone in the fuel rail with silicon free engine oil GM P/N 12345610 (Canadian P/N 993193) or equivalent.
- Lubricate the threads and sealing cone on the NEW fuel injection fuel rail fuel pressure sensor with silicon free engine oil GM P/N 12345610 (Canadian P/N 993193) or equivalent.
- Install the NEW fuel pressure sensor (1) to the fuel injection fuel rail (2) hand tight.
- Remove the NEW fuel injection fuel rail fuel pressure sensor, re-lubricate following steps 1 and 2 above.
- Install the NEW fuel pressure sensor (1) to the fuel injection fuel rail (2) and tighten to 33 N.m (25 lb ft).
- Connect the fuel pressure sensor electrical connector.
- Install the foam insulator from the fuel rails.
- Install the intake manifold. Refer to INTAKE MANIFOLD REPLACEMENT
- Inspect for fuel leaks using the following procedure:
- Turn ON the ignition, with the engine OFF for 2 seconds.
- Turn OFF the ignition, for 10 seconds.
- Turn ON the ignition, with the engine OFF.
- Inspect for fuel leaks.
CAUTION:
Refer to Fastener Caution
