Installation Procedure
- 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 injection fuel rail fuel pressure sensor hand tight.
- Remove the NEW fuel injection fuel rail fuel pressure sensor, re-lubricate following steps 1 and 2 above.
- Install the NEW fuel injection fuel rail fuel pressure sensor (1) and tighten to 33 N.m (25 lb ft).
- Connect the fuel injector wiring harness electrical connector (1) to the fuel injection fuel rail fuel pressure sensor.
- Install a NEW high pressure fuel line. Refer to Fuel Feed Intermediate Pipe Replacement .
- Install the low side fuel pressure service port cap.
- Tighten the fuel fill cap.
- Inspect for fuel leaks using the following procedure:
- Place a sheet of paper towel in between the bottom of the sensor and the top of the generator.
- Start the vehicle and allow the vehicle to idle for approximately 5 minutes.
- Shut the vehicle off.
- Remove the paper towel and inspect the towel for wetting. If wetting is noted repeat steps 1 through 5.
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.
CAUTION:
Refer to Fastener Caution
