Hyundai/Kia 1.1 & 1.4 CRDi (D3FA / D4FC) Remanufactured Delphi Common Rail Injector
D4FC, D3FA
Hard starting or long cranking, especially when hot; rough idle that improves at higher revs; misfire or uneven running under light load; black smoke under load, white smoke on cold start; loss of power and poor fuel economy. When two or more appear together, suspect the injector before peripherals — a comparative leak-off test isolates the failed unit without tear-down.
Excessive injector back-leak preventing rail pressure from building; nozzle wear degrading the spray pattern and causing rough running and smoke; fuel contamination damage — delphi common-rail systems are sensitive to poor-quality diesel. Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
Run a leak-off (back-leak) comparison across all injectors before condemning one — a hard-start with P0087 often traces to a single high-return injector. Delphi injectors carry a C2I/C3I calibration code — register the new code after fitting. Rule out air in the low-pressure fuel system before replacing hardware on cranking-no-start complaints. Use fresh sealing washers and clean the injector seats before refitting. Never condemn a common-rail injector on a fault code alone.
Each remanufactured DFIR00203D is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is calibrated on a common-rail test bench against the manufacturer's specification — delivery, back-leak and response verified — and despatched with a 12 months and its calibration data on file.
The DFIR00203D trusted family covers 9 verified vehicle fitments across 2 makes: Hyundai and Kia. Every fitment listed is registry-verified.
DFIR00203D cross-references 12 further OE numbers, including 28235143, 28540276, EMBR00201D, EMBR00202D, EMBR00203D, HRD357, R00201D and R00202D. Always match the reference etched on your failed unit's body.
