What is a common sign of a failing fuel pump?

A common sign of a failing fuel pump is engine stalling during acceleration. The fuel pump plays a crucial role in delivering fuel from the tank to the engine. When the pump begins to fail, it may not supply an adequate amount of fuel, especially under load, like during acceleration. This lack of fuel can cause the engine to cut off momentarily or stall, leading to a loss of power and potentially dangerous driving conditions.

The other choices do not directly indicate fuel pump issues. Excessive engine noise could suggest problems such as worn components or issues with the engine itself. Increased tire pressure is unrelated to the fuel system and is more related to environmental conditions or improper maintenance of the tires. Irregular exhaust color is often indicative of combustion problems or issues with the engine but not directly linked to fuel pump failure.
