095000-9940 / 8-98246130-0 DENSO Diesel Injector For Isuzu 4JJ1 4JK1

This common rail injector is identified by the dual part numbers 095000-9940 and 8-98246130-0, with the non-hyphenated variant 8982461300 serving as the primary search reference for North American and European parts channels. Engineered as a direct replacement for DENSO 095000 series solenoid injectors, this unit addresses fuel delivery inconsistencies, excessive back-leakage, and rough idle conditions commonly reported in high-mileage Isuzu 4JJ1 and 4JK1 powerplants. Each injector undergoes bench testing for spray pattern, return flow volume, and solenoid response before leaving the warehouse, making it a practical line item for diesel repair shops that need predictable comeback rates rather than open-box surprises.

The table below consolidates the core identifiers, cross-reference numbers, and physical characteristics that procurement staff and counter professionals rely on when confirming fitment against a vehicle's existing injector.

The 095000-9940 serves the Isuzu 4JJ1 and 4JK1 engine families, which underpin a substantial fleet of D-Max pickups, light commercial trucks, and SUV derivatives sold across Australia, Southeast Asia, Europe, and Latin America. These engines occupy a workhorse position in the light-duty diesel segment, powering vehicles that spend their service life in stop-start urban delivery cycles, mixed highway hauling, and moderate off-road duty. The injector also cross-references to applications where the 8-98246130-0 is specified, including certain industrial and agricultural equipment platforms that share the same common rail architecture. For parts distributors, stocking this number alongside related 095000 series references reduces the friction of matching walk-in trade customers who arrive with a pulled injector in hand rather than a clean part number.

Fitting the 095000-9940 demands more than mechanical competence; it requires discipline around high-pressure fuel system cleanliness. Before removal, the injector bore and surrounding cylinder head area should be cleared of debris, and high-pressure lines must be capped immediately after disconnection to prevent particulate ingress. The injector seat requires inspection for carbon tracking or pitting; a compromised seat will compromise the new unit's sealing regardless of component quality. New copper washers and return line seals are non-negotiable on reassembly, and the injector clamp must follow the OEM torque sequence to avoid distorting the solenoid body. Critically, the injector compensation code printed on the unit must be programmed into the ECU using a compatible diagnostic platform; omitting this step invites rough running, elevated return flow, and persistent diagnostic trouble codes that erode customer confidence in the repair.

For diesel repair facilities, the 095000-9940 occupies a pragmatic position between OEM dealer pricing and the uncertainty of untested used components. Injector failure on 4JJ1 platforms typically manifests as cylinder imbalance, white smoke at cold start, fuel dilution in the crankcase, or a P0087/P1093 diagnostic path pointing toward rail pressure deviation. When a back-leakage test confirms injector degradation, replacing the faulty unit with a bench-verified 095000-9940 restores combustion stability without committing the customer to a full set replacement prematurely. This approach keeps the repair invoice defensible while preserving the option to address remaining injectors at a later interval. For parts resellers, carrying this number supports repeat business from shops that service Isuzu-equipped fleets and value a supplier who understands the difference between a common rail injector that works and one that merely fits.

Q1: Does this injector require coding after installation?
A: Yes. The compensation code on the injector body must be entered into the ECU via a diagnostic tool to correct for manufacturing tolerances.

Q2: Can I replace just one injector if the others test within spec?
A: Single-unit replacement is acceptable when the remaining injectors pass back-leakage and spray pattern checks. Confirm cylinder balance after installation.

Q3: What symptoms indicate the 095000-9940 has failed?
A: Look for excessive return flow, misfire under load, fuel in the oil, or a P0087 code with no supply pump fault.

Q4: Is the 095000-9941 a direct interchange?
A: 095000-9941 belongs to the same family and is referenced as an alternate. Verify ECU compatibility before mixing variants in one engine.

Q5: What is the typical warranty on this unit?
A: Warranty terms vary by supplier. Request written coverage specifying return flow and solenoid function as covered failure modes.
