Condition
Some customers may comment on one or more of the following conditions:
- Engine run-on
- Rough idle
- MIL illuminated
Technicians may find DTC P0172 set in the Engine Control Module (ECM).
Cause
This condition may be caused by fuel contamination in the crankcase.
– This may be a result of the high pressure fuel pump leaking fuel into the crankcase when the plunger is depressed.
Correction
If this concern is encountered, perform SI diagnosis and repair as necessary.
- If SI diagnosis does not isolate the cause of this concern, check the low side fuel pressure leakdown with a mechanical gauge as outlined in SI Fuel System Diagnosis.
- If fuel pressure leakdown is present with the J-37287 Fuel Line Shut-off Adapter installed and closed, follow the SI Fuel Pump Replacement Procedure to replace the high pressure fuel pump.
Also change the engine oil and filter to complete the repairs.
