Used Mazda CX-30 Fuel Injection Pump

The CX-30 has been sold as a single generation since its 2019 launch, so the 2021 and 2023 cars share the same generational platform — however, the engine code is the deciding factor above all else, so make sure both cars share an identical engine code (visible on your V5 or via a VIN check) before assuming the pump will swap straight over. Ancillary mounting or bracket changes can occur mid-production within the same generation, so confirm the specific compatibility against your registration with the breaker. Never rely on year alone to guarantee fitment.

Both years sit within the same CX-30 generation (2019-onwards), which is encouraging, but the engine code must match exactly — the CX-30 was offered with different petrol and mild-hybrid units, and a pump from one engine family will not suit another. Because running changes to ancillary components and mounting points can happen across model years even within one generation, you should confirm the part against your specific registration with the breaker rather than relying on year overlap alone.

Trim level — whether SE, SE-L, GT Sport, or GT Sport Tech — has no bearing on fuel injection pump fitment; these are cosmetic and equipment grades, not mechanical ones. What matters is the engine code, fuel type (petrol or mild-hybrid), and gearbox type, all of which should match between donor and recipient vehicle. You may find cosmetic or interior differences between the trim levels on a breaker's stripped car, but those are irrelevant to whether the pump itself fits your vehicle.

The mild-hybrid (M Hybrid) and standard petrol variants use different engine configurations, and the fuel injection pump is not necessarily interchangeable between them even if the displacement looks the same on paper. Always check the engine code on your V5 or via a VIN check and supply it to the breaker, who can confirm whether the donor pump matches your exact setup. Do not assume compatibility based on engine size alone.

The gearbox type can influence fuel injection pump compatibility on the CX-30 because certain engine and transmission combinations were paired with specific fuel system calibrations or ancillary configurations. It is therefore worth telling the breaker both your engine code and your gearbox type when requesting a quote, so they can match the donor car as closely as possible to yours. Engine code remains the primary fitment factor, but gearbox type is a useful supporting detail.

If a Mazda 3 or Mazda 6 shares an identical engine code with your CX-30, there is a reasonable chance the core pump is the same unit, since mechanical parts follow the engine rather than the badge or body style. However, mounting, bracketry, and connector differences can exist between models even with the same engine family, and ECU pairing or immobiliser coding may also be a consideration that you must confirm with the breaker against your registration. Cross-model fitment is genuinely possible but needs to be verified by the breaker rather than assumed.
