How Does a Mechanic Know If There Is a Bad Fuel Pump?
The warnings that you have a car with a faulty fuel pump are that the car intermittently and especially during longer drives. That is because the fuel pump and car have been working extra hard with more pressure and heat.
A faulty fuel pump typically fails when the flow of fuel slows down. When that happens, your engine loses its power. That loss of power is what leads to the stuttering before it just shuts down all together.
The reason why your car can still be turned on again is that once the car cools, the fuel pump will sort of “reset” without all the heat and pressure creating an immediate malfunction. Unfortunately that just means it will fail again and again at more intervals.
How Do You Fix a Broken Fuel Pump?
When roadside assistance encounters a car with a faulty fuel pump, they will attach a special fuel-pressure gauge your car. They do this before test driving it themselves to the stop. They will get an accurate read of when the fuel pump fails and actually the fuel pressure drop as the vehicle fails. That allows them to determine if it needs a simple repair or full replacement.
