WARNING SIGNS OF A BAD FUEL PUMP


The fuel pump in your vehicle does exactly what you would think— it pumps fuel from the gas tank to the engine to power your car. 

Modern vehicles with an internal combustion engine are equipped with an electric fuel pump. Most cars have an in-tank pump mounted within the fuel tank, although some have an inline pump located between the gas tank and the engine.


A failing/failed fuel pump will cause major performance and drivability issues with your vehicle. 

If your car is experiencing any of these bad fuel pump symptoms, bring it in for a vehicle checkup!

 1.THE  CAR WON'T START.

If the vehicle is struggling to start or isn’t starting at all, your fuel pump may be damaged or clogged. If the car still cranks when the key is turned but won’t start, it may be because fuel isn’t getting to the engine. Or if the car starts but requires more than the average number of cranks to turn over, the fuel pump could be at fault then too.

 2. THE CAR SPUTTERS OR DIES WHILE DRIVING.


It’s never a good sign when your car dies as you’re driving. If your engine is sputtering or stalls in the middle of your drive, your fuel pump is likely the issue. The low pressure caused by a faulty fuel pump means that your engine isn’t getting the fuel and air mixture it needs to initiate combustion and power the car. This may be especially obvious when your vehicle is accelerating or under stress (ex: towing a heavy load or driving uphill).

3. THE ENGINE SURGES WHILE DRIVING.

Another common symptom of a bad fuel pump is a surging engine. This is caused by too much fuel being sent to the engine. When that happens, you’ll notice your engine surging—the vehicle will repeatedly pick up speed and then drop speed, even though you haven’t touched the gas pedal or the brake.

 4.YOU  HEAR WHINING IN THE BACKSEAT.

If your fuel tank is making a low-grade whining or whirring noise, that’s a bad sign. Your fuel pump makes a low, barely noticeable humming sound when running normally. 

  5.YOU NOTICE LOWER GAS MILEAGE. 

Another symptom of a bad fuel pump is poor fuel efficiency. Damaged or worn components in the fuel pump can let excess fuel into the engine that goes to waste.

Sometimes the symptoms of a bad fuel pump can be caused by other issues, such as bad fuel, damaged fuel lines or a clogged fuel filter. In any case, you’ll need a comprehensive inspection and diagnosis by a qualified technician to get to the heart of the issue.

Before you start Typically, manual cars will have three pedals: clutch, brake and accelerator (in that order, left to right). The brake and accelerator pedals are pretty simple - press the brake to slow down (the firmer you press it, the quicker you’ll lose speed), while using the accelerator increases the engine’s revs and causes you to speed up (the firmer you press it, the quicker you will speed up).

  HOW TO MAINTAIN YOUR FUEL PUMP Your fuel pump serves as the heart of your vehicle, pumping fuel away and into the parts of the car that need it to do their job  Here are a few maintenance tips that you can follow to make your fuel pump last longer: 1. ALWAYS KEEP YOUR GAS TANK AT LEAST A QUARTER OF THE WAY FULL.  Gasoline works as a coolant for in-tank fuel pumps. If you’re constantly running close to empty, the fuel pump has to withstand more heat, shortening its lifespan. Low fuel levels also require the pump to work harder to move fuel.   2. PERFORM REGULAR FUEL SYSTEM MAINTENANCE. Make sure your fuel system and fuel filters are regularly inspected and replaced when necessary. By scheduling regular maintenance, you can avoid potential issues.

SAFETY FEATURES IN MODERN CARS. Vehicles have become significantly faster and smarter over the last decade, and with these advancements has come the adoption of advanced car safety features. And even with these new features; car accident statistics continue to be alarming. We have compiled a list of car safety features in modern cars. From seatbelts to airbags and anti-lock brakes, the evolution of car safety features has ultimately given us the opportunity to stay safe while on the road. 1. SEATBELTS When it comes to car safety, the seatbelt as to be one of the first features to be introduced. And currently it has come a long way. Resembling a Y-shape, the three-point belt is effective in dispersing the energy of the moving body (over chest, pelvis and shoulders) during a collision. Three-point belts for all seats in a vehicle are now standard. Pretensioning belts are also available in many new vehicles, which tighten instantly on impact to prevent the body from slipping.
