Fiat 500 Fuel Injection Pump Replacement Parts

The Fiat 500 has been produced in a single generation since its 2007 relaunch, with a facelift arriving in 2015, so a 2012 pump and a 2015 pump sit either side of that boundary. Fitment depends above all on the engine code, which you can find on your V5 or via a VIN check, and whether both cars share the same code is the key question to put to the breaker. Confirm compatibility across the 2015 facelift boundary directly with the breaker against your registration before buying.

If both cars carry the same engine code and fuel type, a pump from the early 2007-onwards generation has a good chance of interchanging with a later pre-facelift car, as the mechanical specification follows the engine rather than the model year. That said, ancillary and mounting changes can occur mid-production without a formal facelift, so quote the breaker both engine codes and your registration to get a firm answer. Never assume fitment purely on engine family name without the breaker confirming against the specific codes.

For a mechanical part like a fuel injection pump, trim level — whether Pop, Pop Star, Lounge, or Sport — does not affect fitment; what matters is the engine code and fuel type, not the badge on the back. A pump pulled from a Lounge and fitted to a Pop Star with the same engine code is mechanically equivalent, though you may notice cosmetic differences on the donor car that are irrelevant to the pump itself. Confirm the engine code match with the breaker and you can disregard trim entirely.

Yes, the engine code is the single most important detail for a diesel fuel injection pump, and the 1.3 Multijet engine has been used across several Fiat models, so quoting the exact code from your V5 or a VIN check helps the breaker source the right unit. Fuel type is critical here — a diesel pump is completely different from any petrol equivalent — and ECU pairing or immobiliser coding requirements for the pump are something you must confirm with the breaker, as this varies and cannot be stated as a general rule. Give the breaker your registration alongside the engine code for the most accurate match.

This is a real concern with modern fuel injection pumps, as some applications involve the pump communicating with the ECU or immobiliser system, meaning a used unit may require coding to your specific vehicle. Whether your particular Fiat 500 and engine combination requires this — and what equipment is needed — is something you must confirm with the breaker and, ideally, the garage fitting it, rather than assuming it will be plug-and-play. Factor potential coding costs into your budget before committing to a purchase.

The 500C is the cabriolet variant of the same 500 generation and shares its mechanical underpinnings, so a pump from a 500 and a 500C with identical engine codes and fuel types will generally be the same part. Body style does not affect fuel injection pump fitment — what matters is the engine code, fuel type, and year relative to the 2015 facelift if you are mixing early and late cars. Confirm the engine codes match and check with the breaker against both registrations to be certain.
