095000-9940 Denso diesel fuel injector for Isuzu 4JJ1

The 095000-9940 Denso diesel fuel injector is supplied by Rayfuel as an aftermarket replacement for selected Isuzu 4JJ1 diesel-engine applications and Nissan trucks where the same injector and OE reference are confirmed. It cross-references number 8-98246130-0 and is offered for part-number-matched diesel fuel-system repair. Repair workshops, wholesalers and distributors can find this item in our Denso common rail injector range.

095000-9940 Denso diesel fuel injector identification

• Primary part number: 095000-9940
• OE reference: 8-98246130-0
• Engine reference: Isuzu 4JJ1 diesel engine
• Additional application reference: Selected Nissan trucks
• Product type: Common rail diesel fuel injector
• Product brand: Rayfuel

Use both 095000-9940 and 8-98246130-0 when comparing the replacement with the injector removed from the engine. The Denso wording in the SEO fields identifies the common rail system and buyer search reference; it does not claim that the supplied aftermarket unit is a genuine Denso, Isuzu or Nissan boxed component. The product photographs show the connector, body shape, fuel connection and nozzle area for an initial visual comparison.

Isuzu 4JJ1 and Nissan truck fitment

Isuzu official information identifies the 4JJ1 as a 2.999-liter diesel engine used in light-duty truck applications, including the Isuzu Elf and related N-Series configurations. Injector fitment can still vary according to vehicle model, production year, market, emissions level, engine calibration and injector specification. An engine-family match alone is not enough to guarantee compatibility.

The Nissan truck reference should be treated as a selected-application note rather than a universal fitment claim. Before ordering for a Nissan vehicle, confirm that the existing injector carries 095000-9940, 8-98246130-0 or a verified replacement relationship. Also compare the connector, fuel inlet, mounting profile and nozzle end. Do not select the injector only because the vehicle is described as a Nissan diesel truck.

Common rail injector function

A common rail injector controls the amount and timing of pressurized diesel fuel delivered to the combustion chamber. Correct operation supports reliable starting, stable idle, balanced combustion and normal engine response. A worn, contaminated or electrically faulty injector may disturb these functions, but the 095000-9940 Denso diesel fuel injector should only be replaced after appropriate diagnosis. Isuzu’s official 4JJ1 engine reference provides neutral information about the engine family and its light-duty truck use.

Common signs an injector may need checking

• Hard starting or extended cranking
• Rough idle or uneven cylinder operation
• Reduced power under acceleration or load
• Excessive exhaust smoke
• Abnormal diesel combustion noise
• Fuel leakage around the injector or sealing area
• Injector-related diagnostic trouble codes

These symptoms do not prove injector failure. Similar problems may result from low rail pressure, wiring faults, contaminated fuel, poor compression, air-intake restrictions or other engine conditions. Return-flow measurement, electrical inspection, scan-tool data and professional bench testing may be required before replacement.

Installation and calibration

Installation should be performed by a qualified diesel technician. Keep all high-pressure fuel connections clean, inspect the injector pipe and replace required sealing washers or related service components. Follow the correct tightening information for the exact engine and vehicle. Some Isuzu or Nissan configurations may require injector compensation or calibration data to be registered with compatible diagnostic equipment, while others may follow a different procedure. Confirm the applicable service process instead of assuming coding is always required.

Before you order

Please confirm OE number, engine model or old part photos before ordering. Verify 095000-9940 and 8-98246130-0 against the existing injector, then confirm the vehicle model, 4JJ1 engine specification, production year and market. For Nissan applications, OE-number confirmation is especially important. Send clear photographs and vehicle details through the Rayfuel contact page if you need assistance.

The 095000-9940 Denso diesel fuel injector is intended for OE-number-matched aftermarket replacement in compatible Isuzu 4JJ1 and selected Nissan truck applications. Final fitment depends on exact vehicle and old-part identification.
