Compare Fiat Grande Punto fuel injection system repair quotes from specialist garages

Fiat is known for its small-sized vehicles, like the iconic Fiat 500 and the Fiat Panda, famously one of ex-Top Gear presenter James May's favourite cars. Take a look at our list of top ten cars like the Fiat 500 here.

However, the brand has also branched out from its small-car origins, and in 2023, a Fiat E-Scudo all-electric van set a world record for the longest distance travelled by a van on a single charge, covering just over 311 miles.

Despite the earliest Fiat 500 being released all the way back in 1957, the latest iterations are still making waves, winning 'Best Small Car' at the 2022 Autocar Awards, with its electric counterpart, the 500e, winning 'Best Electric Small Car' at the 2023 WhatCar? Electric Car Awards.

When you accelerate, your car's throttle valve opens, and the fuel injectors spray fuel. How and when this fuel mixes with air depends on what system is used. Petrol engines use an indirect system, where fuel and air mix before entering the combustion chamber, while diesel engines use a direct system, where air and fuel only mix once in the chamber.

Unfortunately, fuel injectors can become clogged over time, in which case you should book a petrol or diesel injector cleaning service or buy a fuel injection cleaning kit.

Signs you may need to have your fuel injectors cleaned include engine misfires, poor fuel economy, rough idling, engine stalls and leaking fuel.

If cleaning the injector system doesn't work, you may need to book a fuel injector repair or fuel injector replacement, depending on the severity of the problem. A fuel injection specialist can offer advice specific to your vehicle.
