Fuel system problems may start with small signs, such as hard starting or an engine that hesitates, and then develop into a complete breakdown. The fuel system supplies the engine with the fuel it needs, in the right amount and at the right pressure. In this article, we explain the main faults, their causes and how they are repaired.
The parts of the fuel system in brief
The system starts at the fuel tank, where the pump draws petrol and sends it through the pipes. The fuel then passes through the filter, which traps impurities, and reaches the injectors, which spray it into the engine. The car’s computer also controls the amount of fuel according to engine speed and load.
Therefore, a fault in any one part of this chain affects the performance of the whole engine. This is why fuel system problems can sometimes show similar symptoms even when the causes differ.
The most common fuel system problems
- A blocked fuel filter: reduces the flow of fuel to the engine.
- A weak fuel pump: can make the car hesitate or stop running.
- A leak in the fuel system: may be caused by damaged pipes or connections.
- Dirty injectors: cause engine shaking and higher fuel consumption.
Signs of fuel system problems
First, watch out for hard starting, especially after the car has been parked for a while. Second, notice any loss of power when climbing hills or overtaking. Fuel consumption may also rise without any change in your driving style.
On the other hand, the smell of petrol around the car is a serious sign you should not ignore. A leak near hot parts may cause a fire, especially in the summer heat of the UAE. Therefore, stop the car and inspect it immediately if you smell this.
Repair and prevention
- Change the fuel filter regularly, following the manufacturer’s recommendations.
- Check the condition of the fuel pump and replace it if it is weak or damaged.
- Make sure there is no leak in the fuel system, and repair any damaged pipes.
- Have the fuel system inspected regularly by a specialist to make sure it is working efficiently.
In addition, avoid driving for long periods with the tank almost empty. The pump relies on the fuel to cool it, so running it on a small amount shortens its life. It is also better to fill up at trusted petrol stations.
Diagnosing these faults accurately needs a fuel pressure measurement and a reading of the engine data. For this reason, computer car inspection helps locate the fault quickly, instead of replacing parts by trial and error. If you are buying a used car, ask for a pre-purchase used car inspection in Sharjah to be sure of the condition of the engine and its systems.
