Reason 1: Cracked Rubber Hose

It’s a very common problem for fuel pumps to have. The rubber hose is prone to cracking because of many reasons. To know if that is the problem you just need to turn the key on.

Then listen to the exhaust pipe of the fuel tank.

You’ll hear the pump start with a buzzing sound then shut off. While this happens you will hear fuel dripping back into the tank.

If that happens then it is the rubber hose that needs to be replaced.

Solution

Replace the rubber hose of the fuel pump. It’ll cost a few cents to buy and then you can fix it yourself. Make sure to buy a perfectly fitted hose to fit your pump.

Otherwise, the problem might persist.

Reason 2: Dirt in the Fuel Tank

If your fuel tank has dirt and debris, it might clog your fuel pump filter.

Which will lead to your fuel pump not working properly. So if it happens then you might have to clean or change the fuel filter.

But there are ways to prevent this from happening. 

Solution

You can use additives to clean your fuel tank. But make sure to not clog your pump filter with the cleaned dirt. Many people make that mistake and end up clogging their fuel pump filters.

Reason 3: Jammed Fuel Pump Filter

A car with very high mileage often runs into this problem. Because of overtime use for a long time, the fuel pump filter gets jammed.

With time the filter gets jammed and restricted with dust and debris. This problem can cause more problems later on for the engine.

Thus solving it as soon as possible is the right thing to do.

Solution

This problem is easily fixable with some cleaners or methods to clean the filter. If it doesn’t work then changing the fuel pump filter will solve the problem. 

To clean the filter first unscrew the fuel lines and set them aside. Then take the filter out and start the cleaning process. Brush off the dust and debris with a brush until it’s clean. 

You can also use adhesive cleaners to clean it faster and more effectively. Once you are done with cleaning the filter, put everything back as it was.

Reason 4: Broken Fuel Pump Fuse

This is a very common problem for the 1998 Chevrolet Silverado. Many times the fuse gets blown because of overload or pump failure.

It can also happen because of a jammed or restricted fuel pump filter. So, the pump won’t be able to deliver fuel to the engine to start. 

Solution

If this problem occurs you just need to replace the fuse. Simply open the fuse box located under the lid of your car.

Take help from the manual if needed to locate the box of fuses. Look for fuses that have their metal strip broken and replace them.

And, that’s all. The fuses are replaced and you are good to go.

Reason 5: Bad Wiring

Wires that are connected to the fuel tank pump must be working. You need to check the wiring and if it’s working. It’s quite easy to do that with a test light.

Solution

Pull out the fuel tank first then the fuel pump. Bring out the wires and test them with voltage testers. If the wires don’t seem to be working then you need to replace the wires.

Reason 6: Faulty Fuel Pump

Sometimes it’s the pump that needs to be replaced. If none of the issues discussed earlier seem to be the problem.

Then the Fuel pump itself is faulty and needs to be changed.

Solution

This is similar to the previous method. Pull out the fuel tank then the fuel pump. You’ll see the fuel pump filter around the middle area.

Lose the two clamps that are connected with the pump. Then unclip the pump and pull it out and put the new one in.
