Used Nissan Primastar Fuel Injector

The Nissan Primastar was only ever sold with diesel engines in the UK — primarily the 1.9 dCi and 2.0 dCi units — and diesel engines do have fuel injectors, so yes, the part exists on this model. However, diesel injectors work very differently from petrol injectors; they are high-pressure direct-injection units, sometimes referred to as common-rail injectors on the later 2.0 dCi variants. Always confirm the exact injector type with your breaker, as the 1.9 dCi and 2.0 dCi units use different injectors and are not interchangeable. Giving the breaker your engine code (found on your V5 or via a VIN check) is the most reliable way to ensure you get the correct unit.

The Nissan Primastar ran as a single generation in the UK from 2002 through to around 2014, sharing its platform with the Vauxhall Vivaro and Renault Trafic throughout. There was a facelift around 2006 which brought changes including the introduction of the 2.0 dCi engine alongside the existing 1.9 dCi, meaning injectors from a pre-2006 1.9 dCi and a post-2006 2.0 dCi are from different engine families and will not cross over. Even within the same engine family across that 2006 boundary, you should confirm with your breaker whether ancillary changes affect injector specification against your exact registration. Engine code is the key detail to supply.

Trim level and body style make no difference whatsoever to injector fitment on the Primastar — the injectors are determined entirely by engine code and fuel type, not by whether the van is SWB, LWB, Panel, or Combi. All Primastar variants sold in the UK used the same diesel engine options regardless of body configuration, so a breaker can match your injector on engine code alone. You may find cosmetic or equipment differences between van grades, but these have no bearing on the mechanical fuel system.

The Primastar shares its underpinnings, engines, and in many cases its drivetrain components with the Vauxhall Vivaro and Renault Trafic of the same generation, and injectors from these badge-equivalent vehicles are frequently used interchangeably in the trade. That said, you must match on engine code rather than badge, as there were specification variations across model years and markets. Always confirm cross-badge compatibility with your breaker against your specific registration and engine code before purchasing, as small production changes can catch buyers out.

Both a 2009 and a 2012 Primastar fall within the post-2006 facelift period where the 2.0 dCi engine was in production, so on the face of it the engine family is the same. However, injector specification can change mid-production run due to emissions or supplier updates, and whether a specific unit from a 2012 vehicle crosses cleanly to a 2009 is something you should confirm with your breaker against both registrations. Supply your engine code — not just the year — as this is the single most useful piece of information a breaker needs to verify the match.

On common-rail diesel systems like those used in the Primastar's 2.0 dCi engine, used injectors often do require calibration data (sometimes called IMA or C2I codes) to be programmed into the ECU to ensure correct fuelling, and fitting an uncoded injector can cause running problems. Whether a specific second-hand injector will need coding to your vehicle is something you must confirm with your breaker and your fitting garage, as this is not something we can state as fact for every unit. A good breaker will often be able to provide any codes associated with an injector they supply, so it is worth asking before you buy.
