My Engine Keeps Losing Power When I Drive Fast
If your automobile’s engine keeps losing power when you try to drive fast, the fuel pump is going bad and is unable to supply the engine with the extra fuel that it. Total Auto Care can replace your fuel pump when it needs it. Aside from power loss at high speeds, here are other signs that the fuel pump is malfunctioning.
Power Loss When Stressed
The engine will also lose power when it is under stress if the fuel pump does not send extra fuel into it. Examples of situations that place the engine under stress include driving up hills or mountain roads that are steep or towing a trailer behind the vehicle. If you have packed your vehicle to the brim, this, too, is extra weight that stresses out the engine.
Unexpected Speed Surges
Aside from causing the engine to lose power, a faulty fuel pump can also cause the engine to increase power unexpectedly. This is a sign that the fuel pump has sent too much fuel into the engine. You may end up with black exhaust alongside the unexpected speed surges.
Reduction in Fuel Economy
All of these things can affect your gas mileage. You will notice that your vehicle does not get as many miles per gallon as it usually gets with a malfunctioning fuel pump. Unfortunately, you will need to fill the tank more often until you have the bad fuel pump replaced.
Reduction in Fuel Pressure
The malfunctioning fuel pump can also reduce the fuel pressure inside the engine. This can cause the engine performance issues discussed above as well as the reduction in fuel economy. The engine relies on fuel pressure that is within a specific range to function efficiently.
Overheating and Stalling
Unfortunately, if the fuel pressure is low, the fuel pump may not be getting enough fuel to keep itself cool. This can make the motor in the fuel pump overheat and, as a result, make your engine overheat. The engine may stall after it gets too hot.
Whining Noises in the Tank
You may also hear whining noises in your fuel tank if the fuel pump is acting up. It’s important to have these noises investigated as soon as possible to avoid the next problem on our list.
Hard Starts or No Starts
This problem is difficulty getting the engine started or ending up stranded with a dead engine. This is a sign that the fuel pump is no longer able to supply the engine with fuel.Total Auto Care in North Branch, MN, is here to help, so schedule a service appointment with us today.
