What's involved
What this repair actually is.
Direct-injection engines use a second, engine-driven pump that raises fuel to extremely high pressure for the injectors; when it wears, you get long cranking, stumbling under load, and low fuel-rail-pressure codes. We replace the high-pressure pump (and its cam follower where applicable), then verify rail pressure meets specification under load.
Symptoms
How you can tell.
- Long cranking before start, especially cold
- Stumble or hesitation under hard acceleration
- Check engine light with low fuel-rail-pressure codes
- Ticking from the pump area that's gotten louder
- Reduced power at highway speed
If you delay
A failing high-pressure pump can leave you with a no-start, and on some engines a worn cam follower will damage the camshaft — a far bigger repair.
