Auto Repair 101: Know the Signs of Fuel Pump Failure Before It's Too Late
If you are an individual who skips service appointments for your vehicle, you will likely need auto repairs at some point. Manufacturers explain you need repair services, but some individuals still drive their vehicles until they experience mechanical failure. It is wise to go beyond the vehicle handbook and get your vehicle routinely inspected by a mechanic. They can detect developing issues before they cause widespread damage to vehicles.
Fuel pumps are car parts that some people pay little or no attention to. This important car part is responsible for distributing fuel to the engines of vehicles. If a fuel pump is malfunctioning, it will give subtle signs that eventually become ominous. Ignoring the signs could result in extensive damage. The following points will help you understand how your vehicle may react to a fuel pump issue.
1. Changes in Fuel Efficiency
Some people use their vehicles for specific tasks each week. This allows them to gauge how much fuel they need to put in their vehicles. If you notice changes in how often you need to refuel your vehicle, it might be an issue with your fuel pump. Ensure you check that there has not been a spike in gas prices.
2. Screeching Noises
Failing fuel pumps may make alarming noises that sound similar to loud screeching. The sound emits during vehicle operation not during idling. It is produced by components of a failing pump working hard to continue fueling a vehicle. Since other mechanical issues can cause screeching noises, it is best to take your vehicle to an auto repair shop whenever you hear strange noises.
3. Unexplained Engine Revving
When you drive normally without attempting to accelerate, your engine should not rev. This is a phenomenon that can occur when a fuel pump is failing. It is dangerous, and it can cause significant mechanical damage to your vehicle. The revving is caused by the fuel pump distributing excess fuel to the engine, and it can flood the engine. A potentially dangerous consequence is a stalled vehicle on the roadway.
4. Stalling or Difficulty Starting
A worn fuel pump will eventually stop working. This usually happens after several ignored signs that a fuel pump is on the verge of failing. Sometimes a vehicle might require several attempts to start, which is indicative that a pump is on the verge of complete failure.
An auto repair shop is a resource where you can determine if you have a fuel pump or other mechanical issues. They can perform visual inspections and use diagnostic machines as necessary.
