Chevrolet Silverado 1500 HD Fuel Pump Assembly

Reasons behind Chevrolet Silverado 1500 HD Fuel Pump Errors

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:

Engine misfiring or stalling

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.

Gas gauge malfunction

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.

Other troubleshooting tips

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.

  • Tips to Keep Your Chevrolet Silverado 1500 HD Fuel Pump in Top Shape

    Crafted to provide optimum performance for your Chevrolet Silverado 1500 HD, the fuel pump is built to supply enough fuel to run the off-road truck on whatever terrain you wish. However, the fuel pump is not immune to wear and tear. So as a result, it may lead to several sorts of problems to your rugged pickup truck. You see, your Chevy may stall or may not even function. To make sure that your fuel pump will deliver efficiently, follow these maintenance tips:

    • Regular checking schedule
    • Ideally, it is best to check your Chevy Silverado's fuel pump at least once in a week or two. Doing so will help diagnose fuel pump issues so you can address them quickly. When servicing the fuel pump, check for hairline cracks or brittleness. If this is the case, it is best to find a replacement to the stock fuel pump right away. Failing to do so could lead to more fuel system repairs and costs.
    • Never let the car run low or run out of fuel
    • To keep your Chevy Silverado's fuel pump in top shape, never let it run low or run out of fuel. In fact, the fuel inside the pump acts as its lubricant. You see, fuel not only propels the vehicle but also keeps the pump in good shape so it is important to keep the pump loaded. If left to dry, the fuel pump may wear at a faster rate.
    • Polish pump lever surface
    • As a maintenance tip, polish the surfaces on the fuel pump lever. You see, the pump lever that rides on the cam can wear easily and may reduce the fuel pump's efficiency. By regular maintenance, you ensure the Chevy Silverado always goes the extra mile.
    • Change filters once in a while
    • The fuel filters' condition affects the fuel pumps' efficiency. If left unmaintained, the filters can get contaminated and become clogged. This could damage the pumps and leave your vehicle thirsty for fuel. So to keep your pumps in shape, schedule a regular cleaning or changing of the filters. This helps your auto run more efficiently.
