Is the Fuel Pump Malfunctioning in your Car

Is the Fuel Pump Malfunctioning in Your Car?
2
The fuel pump is a device that moves fuel from
your tank to the engine, supplying the fuel at a
constant pressure to ensure that your engine runs
smoothly.
3
Depending on the age of your vehicle, you may
have either a mechanical or an electronic fuel
pump.
4
Since mechanical pumps are driven directly by the
motion of the engine and contain few moving
parts, they tend to be reliable and relatively
easy to diagnose and fix.
5
Most problems with mechanical pumps occur when
the diaphragm is damaged in some way, throwing
the pressure system off balance.
6
Electronic pumps are typically linked to
electronic control systems and contain multiple
moving parts and due to increased complexity,
these are more prone to failure.
7
Here are some signs that your fuel pump is
malfunctioning in your car.
8
Car sputters at high speeds
9
It is caused when the fuel pump cant deliver a
smooth flow of fuel to the engine and the engine
receives only air when it was expecting to
receive fuel.
10
This interruption in fuel flow causes your
engine to skip several power strokes, forcing the
engine to sputter and jerk.
11
Less power when accelerating
12
Accelerating requires more fuel, forcing your
fuel pump to work harder and if your pump is
failing, it may not be able to keep up with this
increased demand.
13
If your car acts like its about to stall when
you try to accelerate from a stop, you may need
to have your pump inspected.
14
Losing power while driving uphill
15
Driving roads such as climbing a hill or towing
a load, put an extra strain on your engine and
demand more fuel to deliver the same performance.
16
When your fuel pump is malfunctioning, it isnt
able to maintain a steady flow of fuel to the
engine, resulting in a loss of power.
17
Engine starts to surge
18
When your fuel pump begins to wear out, its
components often wear down at different rates and
this makes the pressure in your fuel lines can
become inconsistent.
19
As a result, drivers may find their cars suddenly
accelerating for a few moments even when they
havent pressed the gas pedal, a condition known
as surging.
20
Engine won't start
21
After ignoring all of the other warning signs of
a failing fuel pump, it will eventually fail
completely.
22
In order to confirm that your pump has failed,
check the pressure in your fuel lines with a fuel
pressure gauge and if it reads zero, then your
pump is dead.
