Key Features
- New MFI fuel injector for gas engines
- Top-feed design with male blade terminals
- Includes O-ring for sealing at the injector body

Detailed Product Overview
Standard Ignition FJ464 is engineered as a direct fuel injector replacement for select Ford Ranger and Mazda B2300 models. The injector uses a top-feed, two-terminal blade connection and is designed to deliver balanced fuel flow for stable combustion, cleaner operation, and reduced fuel system inconsistency. The internal stainless steel calibration components and laser-welded construction are used to improve durability in demanding engine environments. This part cross-references Dorman - HELP 15850 for the same application.
Common Issues This Fuel Injector Can Address
- Rough idle caused by uneven fuel delivery
- Hard starting related to injector wear or poor atomization
- Misfire conditions tied to restricted or inconsistent injector flow
- Fuel odor or leakage from worn injector seals
- Reduced engine response from a failing injector on Ford Ranger or Mazda B2300 applications
Installation Notes and Tips
Verify the injector connector style, top-feed configuration, and terminal layout before installation. Replace the injector O-ring during service and inspect the fuel rail, seals, and surrounding components for wear or contamination. Confirm vehicle application by year and engine setup for 2003-2006 Mazda B2300 and 2004-2006 Ford Ranger models.
Quality Assurance
Standard Ignition manufactures this injector with controlled production from component selection through final assembly.
