The fuel pump functions to supply the fuel from the tank to the engine. This ensures proper combustion of the fuel in the cylinders of your car. A bad fuel pump may be caused due to broken wires or a blocked fuel filter. And some of the common symptoms are loud whining sound and starting problems. See the given slideshow to know all about the major causes & symptoms of a bad fuel pump.

1. Major Causes &
Symptoms of a Bad
Fuel Pump

2. The fuel pump is
commonly regarded as the
heart of the car as it
functions to supply fuel
from the fuel tank to the
engine as a human heart
pumps blood to the whole
body.

3. The fuel pump is
responsible for delivering
fuel from the gas tank to
the engine at the
appropriate pressure
required to meet the
performance demand of
your car.

4. Some minor issues
with the fuel pump
can lead to major
driving and
operational problems.

5. Here are some of the
major causes &
symptoms of a faulty
fuel pump.

6. Broken
wiring

7. In newer cars, mostly
electric fuel pumps are
used which are placed
inside the fuel tank and
depends on the battery for
functioning.

8. Any problem in the wiring
channels, lead to
alteration in the current
or voltage flow from the
relay to the pump. This
may seriously affect the
motor of the pump.

9. Blocked
fuel filter

10. A fuel filter is
necessary to prevent
dirt and other debris
from clogging a car's
fuel delivery system.

11. A blocked fuel filter leads
to low pressure and
reduces the flow of fuel in
the fuel pump, which
severely affects the engine
performance.

12. Low
fuel level

13. When you drive your
vehicle with low fuel
level, results in heating
up the fuel tank much
faster and eventually
overheating the fuel
pump.

14. Also in cold weather,
low fuel level leads to
oxidation of the fuel
tank to form rust. This
rust gets ingested into
the pump, causing its
failure.

15. Loud whining
sounds

16. A typical fuel
pump produces a
much quieter
sound, during
normal operation.

17. Inspection of the pump
should be carried out,
when such strange
sounds occur to prevent
it from more serious
damage.

18. Starting
problems

19. A weak fuel pump is
unable to provide the fuel
to the engine at the
required pressure and
volume, which give rise to
difficulty in starting of
your car.

20. This forces the vehicle
to take more cranks
to start than normal
and in some serious
cases, it even fails to
start.

21. Reduced fuel
efficiency

22. The fuel pumps have a
relief valve that controls
the amount of gas to be
channelized to the
engine.

23. Failure of the valve
leads to overflow of
gasoline in the engine
which directly affects
the fuel economy of
your car.
