Although your Chevrolet Silverado 1500 HD's fuel pumps are engineered to provide a longer service life, they are still susceptible to all sorts of damages overtime. These problems may range from engine stalling to gas gauge malfunction. If you doubt your fuel pump's efficiency, then better pop up the hood and perform some troubleshooting. Listed below are some of the common errors encountered with Chevrolet Silverado 1500 HD's fuel pumps and the reasons behind them:
When you try to start the Chevrolet Silverado but the car refuses to run, check the fuel pump's pressure level. Engine stalling is usually the cause of an imbalance in the fuel pump's pressure. Luckily, there is a wide range of options and tests that you can perform on your pickup truck to diagnose a fuel pump pressure defect. You can use several tests like the dead head pressure test to detect the auto's pump pressure. Your local car shop should have several diagnostic instruments and also their respective manuals as how to use them.
In addition to the fuel pump's pressure, a low fuel volume may also be the reason behind engine misfiring or stalling. You see, if the fuel pump is not delivering enough fuel, then the Silverado will run inefficiently or may not even run at all. Fortunately, low fuel volume is easily detected by inserting a fuel flow gauge into the car's fuel supply lines.
Sometimes when your vehicle's fuel pump malfunctions, the gas gauge also malfunctions. This problem is often attributed to the use of bad gas. You see, this is easily tested by simply running your vehicle. Sometimes, when a fuel pump uses bad gas, the vehicle's gas gauge will stop working. The car will run out of gas without you noticing because the gauge is still showing fuel. When this happens, you'd better change your fuel pump right away to avoid further repairs.
When troubleshooting for fuel system errors like the fuel pump, be sure to perform the diagnosis in a well-ventilated area and away from appliances with open flames. Failing to do so can cause fatal accidents.
