Defective Fuel Pump: The fuel pump pulls the fuel from the gas tank to the engine via the fuel lines.
If the pump stops working, malfunctions, or becomes clogged, it will not supply enough fuel to the injectors.
This can cause the vehicle to accelerate slowly, or even sputter and stall, especially at high speeds.

What does it mean when your car won’t go past 40 mph?
In many cases, when you have an issue with the car accelerating and the check engine light comes on, it’s caused by a mechanical problem with either a drive-system, fuel or ignition system component. The light is triggered when a sensor detects a fault somewhere in the car.
When I step on the gas my car hesitates?
If a fuel pump cannot provide the correct pressure, fuel may have difficulty making it to the engine. A vehicle that hesitates while accelerating or while driving up a hill may have a weak fuel pump. Dirty fuel injectors may cause the engine to run lean which will in turn, cause hesitation when accelerating.
How fast can you go in limp mode?
Limited to one gear and 30-45 mph, you know there is a serious problem with your car’s transmission and you have to get your car to either your dealer or transmission repair shop to have the problem diagnosed and repaired.
What do you do when your car won’t accelerate?
AN IN-EFFICIENT FUEL SUPPLY SYSTEM

Why my car has no power when I accelerate?
There are many reasons why your vehicle may be losing power, especially when accelerating. Some of these common causes are: Mechanical problems such as: Low compression, clogged fuel filter, dirty air filter, clogged Exhaust Manifold. Malfunction of actuators such as: Bad injectors, bad fuel pump, bad spark plugs.
How do I know when my transmission is bad?
Here are five signs of transmission problems you should not ignore:
- Transmission slipping. If you’re experiencing automatic transmission slipping, it can feel like you’re driving in a certain gear and then it changes for no apparent reason.
