Detailed Description

Delphi FJ10631 fuel injector is engineered for precise fuel delivery in gasoline-powered engines and is built as a direct-fit replacement for select GM vehicles. This injector uses a rectangle female connector, two blade terminals, and a clip-style attachment for a secure connection. The included gasket/seal, O-rings, and retainer clips support a proper seal during service. This part cross-references Standard Ignition FJ705 for the same application. If you are replacing a worn injector on a Chevrolet Impala, Malibu, or Pontiac G6, Delphi FJ10631 provides the OE-style fit and function expected in a standard replacement injector.

What It Helps Fix

• Hard starting caused by inconsistent fuel delivery
• Rough idle from a worn or clogged injector
• Misfire conditions related to poor injector spray pattern
• Fuel trim issues from an injector that is not metering correctly
• Fuel odor or leakage at the injector seal area

Installation Notes and Tips

• Verify engine and connector style before installation.
• Replace damaged seals and inspect the fuel rail and injector bore for contamination.
