The fuel pump in late model vehicles is controlled by the PCM ( Power Control Module) or computer. Earlier model vehicles may have a mechanical fuel pump which is controlled by a shaft that is controlled by the cam shaft on most vehicles. The function of the fuel pump is to deliver a constant flow of fuel to the engine.
Common things noticeable if your vehicle needs fuel pump repair. Engine stalls, long crank time to start vehicle, loud humming noise and lack of power. Here at Delta Auto Care our technicians diagnose with the latest diagnostic tools to give you an accurate and correct diagnosis.

Signs your fuel pump is failing
Talking about the most integral component of a car or truck will surely bring fuel pump into the limelight. With the usage of the fuel pump as a key engine component, its failing can be a massive disaster for any driver. As a car or a truck owner, you should be aware of the common symptoms which causes the fuel pump to fail. Below, you will get to know the top signs of a failing fuel pump.
The Engine Sputters at High Speed
If you are a driver your car’s has high-speed sputtering issues, there is a high possibility of your fuel is not properly reaching its end goal. The car may run pretty well for several miles and then begin to jerk before returning to its normal state.
What does it mean?
Some mechanics might state the issue as one with a “dirty gas” problem with an almost empty gas tank. While this may be the case, effectively having difficulty suppling a consistent level of fuel at a higher steady state, the actual reason is probably due to the loss of pressure which indirectly causes the engine to sputter, and as a result, the car is jerky at top speed.
While accelerating, the vehicle loses power
This symptom is quite similar to the previous one where the vehicles will be in a jerky state during acceleration from a stop. In this symptom, your car may produce a loud sound and then accelerate smoothly.
Once you release the brake and hit the gas pedal, the flow of gas releases fuel to accelerate. The malfunctioning of the car fuel pump results in an decreased flow which restricts acceleration power.
Once the total pressure is refilled, the engine comes back to its original state, and the car begins to run smoothly.
A sudden loss of power when vehicle is in a stressful state
Usually, any car or truck engine is put under tremendous stress even for simple driving. Forward movement is sometimes hindered by some external forces like towing a trailer or going up a steep hill. If the vehicle loses power and begins to sputter, the fuel pump is the likely component which is the cupret.
An aging pump can maintain a healthy fuel state when operated and controlled under normal conditions. However, sometimes the resistance is created, and this leads to power loss altogether.
If you are experiencing loss of power or jerky movement while driving, bring you vehicle in to us for an auto tune up service.
