Isuzu 4JJ1-TC 3.0 Remanufactured Common Rail Diesel Injector
4JJ1-TC, 4JJ1-TCX
Hard or extended cranking; rough or lumpy idle; white, blue or black smoke; hesitation under load, poor fuel economy, diesel knock or rattle; occasional stalling or limp mode. When two or more appear together, suspect the injector before peripherals — a comparative leak-off test isolates the failed unit without tear-down.
Injector wear or internal leakage — balance/compensation values drift out of specification before major drivability symptoms appear; leaking injector diluting the engine oil (rising level, diesel smell in the sump); injector back-leak dragging rail pressure down on high-mileage engines. Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
Read injector balance / compensation values — one cylinder far from the others identifies the failing unit early. Check the engine oil for diesel dilution; a rising level points to a leaking injector on this engine. Run an injector leak-back test on hard-start or P0087 complaints. Denso injectors carry an ID code — register the new code after fitting. Never condemn a common-rail injector on a fault code alone.
Each remanufactured 095000-6980 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-month parts warranty and its calibration data on file.
The 095000-6980 trusted family covers 4 verified vehicle fitments across 3 makes: Chevrolet, Holden and Isuzu. Every fitment listed is registry-verified.
095000-6980 cross-references 6 further OE numbers, including 8-98011604, 898011604, 8-98011604-1, 8-98011604-5, 095000-6983 and DCRI107800. Always match the reference etched on your failed unit's body.
