Detailed Description
Standard Ignition FJ693 is engineered as a replacement fuel injector for Ford and Mazda fuel injection systems that use a top-feed MFI design. The injector’s stainless-steel calibration slide and spring assembly helps reduce corrosion inside the fuel control body, while the precision-wound solenoid windings allow the engine computer to command fuel delivery with greater consistency. High-temp Viton O-rings are included to maintain sealing performance in demanding heat conditions. This part cross-references Bosch 15558 for the same application.
Compatible With 1996 Ford Aerostar, N/A; 1993-1996 Ford Explorer, N/A; 1993-1996 Ford Ranger, N/A; 1994-1996 Mazda B4000, N/A; and 1993-1994 Mazda Navajo, N/A.

Common Issues This Part May Address
- Rough idle caused by inconsistent fuel atomization
- Hard starting related to restricted or weak injector performance
- Fuel delivery imbalance that can affect drivability
- Corrosion-related injector wear inside the fuel control body
- Heat-related sealing concerns at the injector O-rings
Installation Notes and Tips
Verify the injector connector style, terminal count, and top-feed system layout before installation. Inspect the fuel rail, seals, and surrounding components for contamination or wear, and replace damaged O-rings during service. Confirm vehicle-specific fuel system requirements for Ford Explorer, Ford Ranger, Mazda B4000, and Mazda Navajo applications before final assembly. The FJ693 should be installed with clean fuel system surfaces to help maintain proper sealing and electrical connection.
