• Description:

  This is a genuine Ford electronic fuel injector for the 2.3L four-cylinder engine, the solenoid-operated valve that meters and atomizes pressurized fuel into the intake port on each intake event in response to the powertrain control module. It fits 1995 through 1997 Ford Ranger trucks equipped with the 2.3L engine, seating into the fuel rail and intake with its supply O-rings to deliver a precise spray pattern for clean combustion. A clogged, leaking, or electrically failed injector causes a rough or unstable idle, a cylinder misfire, hard starting, hesitation or stumble under acceleration, elevated fuel consumption, a fuel odor, an illuminated check engine light, and lean or rich fuel-trim trouble codes. Each cylinder uses its own injector, and replacing a failed unit restores balanced fuel delivery and smooth running across the rail. This genuine Ford injector matches the original flow rate, spray angle, and electrical resistance so fuel trims stay within the factory calibration and the engine meets its original driveability and emissions targets, which an out-of-spec substitute can upset. It is supplied as a new component rather than a remanufactured core. Replace the inlet and lower O-ring seals during installation and lubricate them lightly with clean engine oil to prevent pinching, then verify there are no leaks at the rail once fuel pressure is restored. Ordering by the Ford part number ensures the correct injector for the 2.3L Ranger application and avoids the larger-bodied V6 injectors used elsewhere in the lineup.
