What are the signs of a malfunctioning fuel pump in a Vauxhall Vivaro?

I've been having issues with my Vauxhall Vivaro lately and I suspect it might be due to a faulty fuel pump. What are some common signs that indicate a problem with the fuel pump?

The fuel pump is responsible for delivering fuel to the engine, so if you notice that your vehicle is having trouble starting or is hesitating while accelerating, it could be a sign of a malfunctioning fuel pump.

Another sign of a faulty fuel pump is a sudden decrease in fuel efficiency. If you find yourself needing to fill up more frequently, it could be because the fuel pump is not delivering enough fuel to the engine.

You may also notice strange noises coming from the fuel tank, such as a whining or buzzing sound. This could indicate a problem with the fuel pump and should be checked by a mechanic.
