Unresponsive Throttle

If your throttle is unresponsive, it could be a sign of low fuel pressure. If there’s not enough pressure to push fuel through the injectors, then the engine won’t be able to create enough power to accelerate. This problem will usually get worse the more you try to press on the gas pedal.

Rough Idle

If your engine is idling roughly, it could be a sign of low fuel pressure. Low pressure can cause the fuel to atomize poorly, which will result in an uneven mixture of air and fuel in the cylinders. This can lead to a loss of power and a rough idle.

Difficulty Starting the Car

If your car is having difficulty starting, it could be due to low fuel pressure. If the pressure is too low, the injectors won’t be able to deliver enough fuel to the engine to start it. This problem will usually get worse in cold weather.
