DIAGNOSIS
1. With the hood open, listen for chirping with the engine warmed up. Click HERE to hear an example.
•
If the noise is coming from the high pressure fuel pump, go to REPAIR PROCEDURE.
•
If the noise is not coming from the high pressure fuel pump, continue with normal troubleshooting.
REPAIR PROCEDURES
1. Relieve the fuel pressure. See service information.
2. Set the No. 1 piston at top dead center (TDC). See service information.
3. Remove the intake manifold and intake manifold base. See service information.
Page 2 of 7
4. Remove the high pressure fuel pump cover.
5. Remove the quick-connect fitting cover.
6. Disconnect the quick connect fitting.
7. Remove the fuel joint pipe.
Page 3 of 7
8. Disconnect the high pressure fuel pump connector.
9. Remove the bolts by loosening them alternately, then remove the high pressure fuel pump and the roller.
10. Rotate the crankshaft and check the high pressure fuel pump cam for pits, scores, and excessive wear. If needed,
replace the rear camshaft.
11. Set the No. 1 piston at top dead center (TDC).
12. Install the roller onto the high pressure fuel pump cam.
13. Set the gauge on the roller and hold it, then set the dial to zero.
14. Rotate the crankshaft 720° and measure the three cam lobes height. If the cam lobes are excessively worn, replace
the rear camshaft.
NOTE
The high pressure fuel pump cam has three cam lobes. Cam Lobe Height Standard (New): 0.236 in (6.0 mm)
15. Set the No. 1 piston at top dead center (TDC).

16. Check the position of the cam that drives the high pressure fuel pump as shown.
17. Coat the roller, O-ring, cam and around the bore of the lifter with clean engine oil.
18. Install the roller and the high pressure fuel pump. Install the bolts loosely by hand in an alternate pattern. Connect
the connector.
NOTE
Failure to install a new fuel joint pipe will cause fuel leaks.
19. Lubricate the top of the new fuel joint pipe and the threaded area of the fuel rails and the high pressure fuel pump
with polyethylene glycol included in the new fuel joint pipe kit.
NOTE
Do not reuse the fuel joint pipe.

20. Tighten the fuel joint pipe nuts by hand until the end of the joint pipe is seated on the fuel rails and high pressure
fuel pump.
21. Set the fuel joint pipe bracket on the cylinder head and loosely install the bolts.
22. Tighten the high pressure fuel pump mounting bolts to the specified torque.
23. Tighten the fuel joint pipe bracket mounting bolts and the fuel joint pipe nuts to the specified torque in the numbered
sequence shown.
NOTES
•
A crowfoot-type special tool increases the torque applied by the torque wrench. Search Torque Specifications on
the iN for details on how to recalculate the torque wrench setting.
•
Failure to tighten the fuel joint pipe nuts to the proper torque will cause a fuel leak.
24. Connect the quick-connect fitting and install the quick-connect fitting cover.
25. Set the power mode to ON, but do not start the engine. After the fuel pump runs for about two seconds, the fuel line
will be pressurized. Repeat this two or three times, then check for fuel leakage.

26. Install the high pressure fuel pump cover and torque it to 12 N·m (9 lb-ft).
27. Install the intake base and intake manifold.
