What are the reasons for insufficient fuel in the Chevrolet Trax?

[Steph]

Here are the reasons for insufficient fuel in the Chevrolet Trax: 1. It is recommended to check the fuel pump. If the fuel pump that initially draws gasoline has a problem and does not draw enough gasoline, it will cause the fuel pressure of the entire system to be too low. 2. The gasoline filter is clogged. Improper maintenance can lead to clogging, which affects fuel pressure. Since the fuel filter is located behind the fuel pump and is responsible for filtering impurities in the fuel, if impurities accumulate or block the filter, fuel cannot pass through the filter in time, thus affecting fuel pressure. Additional information: Due to insufficient fuel pressure, the fuel injected by the injector cannot reach the predetermined value, which affects the combustion efficiency of the cylinder, leading to unstable idle speed or weak acceleration.
