Fuel pump replacement cost: $843 to $1,160, including parts and labour
The fuel pump in a Chevrolet Cavalier is responsible for delivering gas from the fuel tank to the fuel injectors. The pump must supply enough fuel at a high enough pressure to keep the engine running smoothly. A failing fuel pump may cause the car to lose power, keep stalling, or not start or run at all. Other signs that your fuel pump needs replacing include a loss of performance and fuel economy, as well as engine flooding.
Fuel pump replacement in a Chevrolet Cavalier costs on average between $843 and $1,160, including parts and labour. This can vary from car to car and does not include taxes and fees or your unique location. Labour costs are estimated between $159 and $200, while parts are priced between $684 and $960.
Fuel pumps can be located either inside or outside the fuel tank. Replacing a fuel pump inside the fuel tank involves removing an access cover, while replacing a pump outside the tank requires disconnecting the fuel lines. In some cases, fuel will need to be drained before removing the access panel. After replacing the pump, a mechanic will check for fuel leaks and ensure the problem is solved.
Given the risk of fire when working with the fuel system, it is recommended that fuel pump replacement be left to professionals. A proper diagnosis can also save you money, as a clogged fuel filter or bad circuit can cause symptoms identical to a faulty fuel pump.

Fuel injectors: replacement cost is between $331 and $366
Fuel injectors are responsible for regulating the amount of pressurised fuel used for each of your Chevrolet Cavalier engine's cycles. There is one injector per cylinder in the engine. Each time an intake stroke occurs in the engine, the vehicle's computer sends a signal to the fuel injectors, requesting that they spray fuel. For heavy acceleration, the duration of the fuel spraying will be longer than if the engine is idling.
Fuel injectors tend to fail after 80,000 miles and require little maintenance. To prolong the life of the fuel injectors, it is recommended to follow the scheduled maintenance schedule for cleaning the fuel delivery system and injectors. If your fuel injectors are failing or clogging, engine power will be reduced and misfires will occur.
When replacing fuel injectors, it is important to use high-quality, OEM parts. Keeping the injectors the same will ensure even power across the engine and a proper air-fuel mixture for all cylinders. This should result in a smooth-running engine. Working with fuel is dangerous, and it is recommended that fuel injector replacement be left to a professional. The risk of fire is significant, but this repair can also get very complicated. A good amount of knowledge is required to remove the injectors, intake manifold, fuel rail, and other components, and if done incorrectly, it can further damage your Chevrolet Cavalier.
The average cost for a Chevrolet Cavalier Fuel Injector Replacement is between $331 and $366, but this can vary from car to car. Labor costs are estimated between $91 and $115, while parts are priced between $240 and $251. This range does not include taxes and fees and does not factor in your unique location.

Fuel filter: a clogged filter can cause a loss of performance
The fuel pump in a Chevrolet Cavalier is responsible for delivering gas from the fuel tank to the fuel injectors. The pump delivers fuel at a high enough pressure to keep the engine running smoothly. A failing fuel pump can cause the car to not start or run, leading to a loss of performance.
One sign of a failing fuel pump is a loss of performance and fuel economy caused by decreased fuel pressure. Engine flooding can also occur when the relief valve won't close, resulting in too much fuel being released. In some cases, the car may experience increased fuel consumption or frequent flooding.
A clogged fuel filter can also lead to a loss of performance. Symptoms of a clogged fuel filter include a loss of power during hard acceleration and the "Decreased Engine Power" warning light illuminating. When the demand for fuel is not too great, the engine will run normally once the accelerator is released.
For the Chevy Cavalier, a clogged fuel filter may cause the car to become harder to start. In some cases, the car may die while driving and then refuse to start after sitting overnight. A strong raw gas smell may also be present when the car has been turned off for at least two hours.
The cost of replacing a fuel pump in a Chevrolet Cavalier ranges from \$843 to \$1,160, including parts and labour. The cost of replacing fuel injectors ranges from \$331 to \$366. It is recommended that fuel pump and injector replacements be left to professionals due to the risk of fire and the complexity of the repairs.
