Used Vauxhall Vectra Fuel Injector

Yes, fuel injectors are fitted to all petrol Vectra engines and to diesel variants that use direct or indirect injection — in practice, every production Vectra engine uses injectors in some form. The design and specification of the injector differs significantly between petrol and diesel, and between individual engine codes, so you must know your fuel type and engine code before sourcing one. Check your V5 or run a VIN check to confirm both.

The Vectra B ran from 1995 to 2002 and the Vectra C from 2002 to 2008, and these are distinct generations with different engine families, so injectors do not carry over as a rule. Even where an engine code looks similar across the two generations, the injector body, connector, and flow rate may differ. Treat the generation boundary as a hard stop and confirm any cross-generation swap directly with the breaker against both registrations.

Trim level — whether LS, Comfort, Elegance, Design, SRi, or GSi — has no bearing on injector fitment whatsoever; injectors follow the engine code, not the badge. Two Vectra Cs with the same engine code will use the same injector regardless of trim. The only cosmetic difference you might notice is that a dismantled SRi or GSi may carry sports-specific ancillaries nearby, but the injectors themselves are identical if the engine codes match.

The Vectra C received a facelift in 2005, after which some engine variants were updated, so the answer depends on whether your specific engine code changed at that point. If the engine code on your 2004 car matches the code on the 2006 donor car, fitment is likely, but ancillary and connector changes mid-production can catch you out. Confirm the exact engine codes with the breaker against both registrations before buying.

No — body style is irrelevant to injector fitment on the Vectra. Injectors are determined entirely by the engine code and fuel type, and the same engine was available across saloon, estate, and hatchback bodystyles. Just supply your engine code and registration to the breaker and ignore body style when comparing donor vehicles.

Injector coding and ECU pairing requirements vary by engine type and can affect how the engine runs after a swap, particularly on later common-rail diesel engines where injector trim codes may need to be programmed in. Whether your specific Vectra requires this is something you should confirm with the breaker or your fitting garage before purchasing, as it affects both the cost and complexity of the job. Never assume a direct plug-and-play swap without checking first.
