5 Symptoms of a Clogged or Faulty Fuel Filter
great vehicle that starts and runs as smoothly as possible is admired by
everybody. But what if your vehicle isn't working correctly one day, with the
check engine light on or the engine misfiring? Most likely, you have a blocked
or faulty fuel filter.
can you know whether your fuel filter is blocked or faulty? The most common
signs that you need a new fuel filter are difficulty starting, a check engine
light, or reduced performance. It's possible that your engine can stall or
misfire as you accelerate.
you experience any of the following symptoms, check MOT status
and book your car in with a car repair garage to investigate what the issue is
and repair it to avoid an MOT failure.
it true that you wouldn't drink stream water that hasn't been filtered? Why is
this the case, though? Because it's commonly infected with pathogenic microbes!
The same can be said of the fuel we put in our cars, which, thankfully, flows
through a filter before reaching the engine.
Symptoms That Your Fuel Filter Must Be Replaced
following are signs that your fuel filter needs to be replaced in your vehicle:
1. Starting Issues - Here's
what you should do if you can't get your vehicle to start. A number of factors
might cause an engine to fail to start, including broken spark plugs, a dead
battery, or an alternator failure. It might also mean that there isn't enough
fuel in the combustion chambers. Before scheduling your next MOT testing service, get
this problem assessed and rectified by a car mechanic.A low PSI pressure test
will reveal if your fuel system has a problem, such as a malfunctioning fuel
pump, blocked injectors, or a clogged fuel filter. Though an engine that won't
start isn't the first indicator of a blocked fuel filter, it is the most common
symptom. Make sure it's related to any of the symptoms listed below. If that's
the case, consider yourself fortunate because the other causes of your engine's
failure are significantly more expensive to fix.
2. The Check Engine Light Is
Coming On - If you're like most vehicle owners, the "check engine"
light is something you dislike. Sure, it means a repair bill is on the
way, but it also guarantees that things don't become worse to the point where
there's significant damage. The check engine light might come on for a variety
of reasons. Many modern vehicles, thankfully, have built-in pressure sensors
that will emit a particular code if there is a problem with the fuel system. If
you check MOT history
online and discover that your car failed the MOT because of the engine
management light, the fuel filter might be to blame.
3. Engine Stalling - A
shortage of fuel, power, or air is the most common cause of engine stalling.
With this in consideration, it really should come as a shock that your engine
may stall if there isn't enough fuel flowing through it. If you complete an MOT history check and
realise that the MOT tester failed the MOT as unable to carry out the checks,
the fuel system could have been at fault. Because there is likely still
fuel in the fuel lines, your engine may start right away. When you speed or
confront a steep uphill, the problem arises since more is required as you push
the pedal. When towing a load, the engine needs to work harder to carry the
weight, which requires more fuel. Many reasons can cause an engine to stall, so
keep an eye out for any of the other symptoms listed below.
4. Misfires in the Engine -
Simply explained, a misfire occurs when an error occurs in one of the
combustion chambers, causing the engine to skip a step. Damaged spark plugs, a
broken ignition coil, or a malfunctioning camshaft sensor are just a few of the
factors that might force an engine to misfire. However, before reaching the
fuel injector, the fuel must pass through the fuel filter. It can also cause
the engine to misfire if it is delayed for any reason. This is particularly true
when you put extra pressure on your car, such as when you accelerate, carry a
load, or drive up a steep slope. This is commonly felt like a minor jolt when the
engine skips a beat, usually accompanied by a delay in power delivery.
5. Engine Performance Drops -
A decline in engine performance is another indicator of a faulty or clogged
fuel filter. This is generally most obvious while speeding, pulling a burden,
or driving up a steep slope, similar to the latter two symptoms. When the ECM
detects a shortage of fuel being delivered to the injectors, it reduces power
to prevent any harm. While this does not always indicate a blocked fuel filter,
it certainly raises the possibility. Especially if this symptom appears to be
related to others on the list.
