Q: My 2001 Alero fuel pump is working on and off, why is this happening?

Answer: If your fuel pump is working intermittently, there are a few reasons why this might be happening. Firstly, you might have luck by replacing the relay. The relay powers the fuel pump when you press on your pedal. If the relay is not functioning as well as it should, it may cause the fuel pump to not always work. Next, a loose connection between the positive and negative terminals and coils could cause intermittent functioning of the fuel pump. Also, your fuel pump might not be grounded properly, causing it to work on and off. Lastly, the contacts in the fuel pump relay can wear down and cause the fuel pump to not function properly. Overall, start by replacing the fuel pump relay if these are the symptoms you are experiencing.
