Quick facts
- Part: Delphi FP10299 fuel injection pressure regulator
- Fits: 2002-2005 Chevrolet Trailblazer 6-cylinder 4.2L and other vehicles
- Condition: New
A failing regulator can show up as hard starting, a rough idle or poor fuel economy. A weak fuel pump can produce similar symptoms, so these signs alone do not prove the regulator is at fault.
