7 Ways You Can Tell Your Fuel Pump is Failing
A failing fuel pump is a dangerous hazard for a car and anyone driving one. Recognize these signs and you can save yourself a fortune on repairs and a potentially life-threatening situation.
A fuel pump is a device that regulated the pressure of fuel supplied from the gas tank to the carburetor. Mechanical fuel pumps were once the reigning technology of the past. Car manufacturers abandoned them in the 80’s for the electronic fuel pump that provided four times the pressure of its mechanical counterpart. This performance boost is innovative, but electronic fuel pumps are notorious for breaking down. Here’s what to look for to diagnose a failing fuel pump.
1. Sputtering, Jerking or Misfiring at High Speeds
This is a very good indicator. When driving on a highway at a constant speed you car may drive normally for around 15 kilometers before sputtering. This is only brief as the vehicle resumes its driving performance in a regular fashion. Though many people often confuse this with the knocking effect of using low-quality fuel, it could quite possibly indicate the momentary loss of fuel pressure. You may need to find some in-depth facts about fuel pump failure, to get to know why this happens.
2. Losing Power Midst Exertion
Climbing a hill, towing a heavy load, or even accelerating from zero can push your car to its limits. Losing power at these times can be fatal. A faulty fuel pump may not regulate enough pressure and cause you to lose power. You may hear a stalling sound when this happens. Also, when parked and revved failing fuel pump sounds whiny.
3. Surging Unexpectedly
Quite the opposite of what we just mentioned earlier, you may experience a sharp acceleration without even depressing the gas pedal. The fuel pump may have an irregular resistance within its motor, caused by a lack of electricity to keep the pressure at optimum levels. The release of the sudden build-up in fuel pressure throttles the car forward faster than you may have intended. This is risky if you’re tailgating anyone. If you ever experience this, you can troubleshoot your fuel pump or simply bring it to the fuel pump experts in JB.
4. Rising Temperature of the Engine
If you find your car stalling when you care overheats, it’s a clear warning sign of a failing fuel pump. If it keeps on stalling, this means your fuel pump is deteriorating fast. Watch the temperature gauge like a hawk.
5. Fuel Pressure Gauge
Keeping an eye on the fuel pressure gauge lets you know if your engine is getting enough fuel. Check the owner’s manual to see what the optimum fuel pressure is for the car. Check the fuel gauge when someone else revs the car. If it’s lower than optimum, this is a warning sign.
6. Low Fuel Economy
If you notice that your car goes from fuel efficient to fuel hungry, then it might be time to get a closer look. Electronic fuel pumps usually have a relief valve that restricts too much fuel from flowing into the carburetor. If the relief valve doesn’t work properly then your fuel consumption increases substantially. If you want to maintain fuel economy in your car superchargers help your engine save fuel. Fuel efficiency is also a perk of a turbocharger. It’s probably best to find out what’s better for your make and model: turbochargers vs superchargers.
7. The Engine Won’t Start
This is a result of ignoring the above-mentioned warning signs. When attempting ignition, You’ll find that your engine might crank but never ignite. Only a professional can fix the damage who knows how to test your fuel pump. Be ready for a stiff bill because the damage caused is substantial.
Head the warning signs. Remember: ignoring this can be dangerous or even fatal.
