Fuel system faults can quickly turn a reliable vehicle into one that struggles to start, hesitates under acceleration, or consumes far more fuel than it should. Because the fuel system controls how fuel is delivered, measured, and burned, even minor issues impact drivability and performance.
The "Old Way" of fixing this usually involves risking a breakdown on the way to a garage or paying for a tow truck just to get a diagnosis.
Maxamy Mobile Autocare offers the "Smart Way." We provide professional mobile fuel system repairs directly at your location.
We use professional diagnostic equipment to identify the root cause, whether it's a blocked filter or a failing pump, and fix it on-site to minimise disruption to your day.

If your car feels different or is costing more to run, your fuel system may be compromising performance. Look out for these common symptoms:
Hard Starting: The engine cranks over but struggles to fire, or takes several attempts to catch before running.
Hesitation/Flat Spots: You press the accelerator, but there is a distinct delay or "stumble" before the car responds.
Whining Noise: A noticeable high-pitched whine coming from the rear of the vehicle (often the fuel pump struggling).
Rough Idle: The car shakes or feels unstable when sitting at traffic lights, suggesting uneven fuel delivery.
Fuel Smell: A strong odour of raw petrol or diesel inside or outside the cabin, indicating a potential leak.
Engine Warning Light: The "Check Engine" light appears on the dashboard, often triggered by sensor readings like "System Too Lean" or "System Too Rich".
We offer fuel system repairs strictly limited to specific services to ensure accuracy and mobile suitability. We retain the full technical scope to ensure accurate diagnosis and repair.
We address issues affecting how fuel is supplied from the tank to the engine. This includes fuel pump repair for pumps that whine, struggle under load, or cause power loss while driving. We also carry out fuel filter changes where restricted filters are limiting flow and affecting performance. In addition, we handle fuel tank repairs to resolve leaks or integrity issues that compromise safe and consistent fuel delivery.

We perform fuel injector repairs to resolve clogged or malfunctioning injectors that cause misfires, rough idling, or poor fuel economy. We also carry out fuel pressure regulator replacement to correct pressure fluctuations that can lead to hard starting, hesitation, or excessive fuel consumption.

We carry out throttle body repairs to address carbon buildup or mechanical faults that restrict airflow and cause uneven idling or poor throttle response. We also perform inlet manifold gasket replacement to prevent unmetered air leaks that disrupt combustion and trigger performance issues or warning lights.

We replace faulty mass air flow (MAF) sensors that provide incorrect airflow readings, often leading to poor acceleration, reduced fuel efficiency, or engine warning lights. We also carry out throttle position sensor replacement where inaccurate input data causes jerky acceleration or inconsistent power delivery.

Fuel system repairs focus on components that deliver, regulate, and control fuel and airflow into the engine. This includes fuel pump repair, fuel filter changes, fuel tank repair, fuel injector repair, fuel pressure regulator replacement, throttle body repair, inlet manifold gasket replacement, and replacement of airflow and throttle position sensors.
Common symptoms include difficulty starting, loss of power, hesitation under acceleration, rough idling, engine misfires, poor fuel economy, or engine warning lights. These issues are often linked to fuel delivery faults, pressure regulation problems, injector issues, or incorrect airflow readings.
Yes. Fuel system issues are diagnosed before any parts are replaced. Many symptoms overlap across different components, so accurate diagnosis is essential to identify whether the fault lies with fuel delivery, pressure regulation, injectors, airflow, or sensors, rather than replacing parts unnecessarily.
Yes. Faults such as failing injectors, incorrect fuel pressure, air leaks, or faulty airflow and throttle position sensors can all trigger engine warning lights. Identifying and repairing the underlying fuel system issue helps restore correct engine management operation.
Yes. Fuel pump repairs are carried out where pumps are noisy, struggling to maintain pressure, or causing power loss. Fuel injector repairs address issues such as clogging or malfunction that lead to misfires, uneven running, or reduced performance.
The throttle body controls how much air enters the engine, while sensors such as the mass air flow sensor and throttle position sensor provide data used to calculate fuel delivery. Faults in these components can cause hesitation, rough idling, or jerky acceleration and are repaired or replaced where required.
Yes. Fuel system repairs are provided as a mobile service where possible and can be carried out at your home or workplace. This includes most fuel delivery, injection, sensor, and throttle system repairs, depending on vehicle access and fault severity.
Fuel system repairs do not include engine internal work, ECU programming, emissions system repairs, or full fuel system overhauls. The service is focused on specific, serviceable fuel and air intake components that directly affect drivability, efficiency, and reliability.
