Title: Major Causes & Symptoms of a Bad Fuel Pump
1Major Causes Symptoms of a Bad Fuel Pump
2The 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 CAUSES
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.
8Any 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.
9Blocked fuel filter
10A fuel filter is necessary to prevent dirt and
other debris from clogging a car's fuel delivery
system.
11A blocked fuel filter leads to low pressure and
reduces the flow of fuel in the fuel pump, which
severely affects the engine performance.
12Low fuel level
13When you drive your vehicle with low fuel level,
results in heating up the fuel tank much faster
and eventually overheating the fuel pump.
14Also 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.
15SYMPTOMS
Loud whining sounds
16A 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.
18Starting problems
19A 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.
20This forces the vehicle to take more cranks to
start than normal and in some serious cases, it
even fails to start.
21Reduced fuel efficiency
22The fuel pumps have a relief valve that controls
the amount of gas to be channelized to the
engine.
23Failure of the valve leads to overflow of
gasoline in the engine which directly affects the
fuel economy of your car.
