Electric Fuel Pumps – Understanding the Causes Behind Their Failure

The working of the modern car is not the simple burn-fuel-in-engine-to-turn-wheels machine anymore. Vehicles these days have become much more advanced than what they used to be at one point of time. In fact, cars these days have become complicated pieces of technology with more and more contraptions becoming a part of the machinery. New innovations in the field of engineering have allowed automobile designers in coming up with more fuel efficient systems. The electric fuel pump is one of these devices that are necessary to help you in getting the most out of your car.

The fuel pump happens to be one of the most important components of a vehicle’s engine system. Any malfunction in this device can actually get the car to stop working completely. No fuel means nothing to burn in the car engine which in turn means to movement. Let us examine the various reasons that can cause an electric fuel pump to stop working.

Broken wiring

Faulty wiring in the vehicle’s fuel system can prevent the flow of gas to the engine, thereby causing a malfunction. There will usually be an obstruction in the current flow from the fuel pump from the relay. Even the corroded, loose, melted or burnt wires/connectors, and poor electrical grounding can restrict the current or voltage flow from the relay to the fuel pump, thus, affecting its functioning - pumping fuel to the engine.

Fuel tank issues

This is another common reason behind the malfunctioning of electric fuel pumps. The presence of dust particles, debris, rust or other forms of contaminants can cause the fuel pump to stop working properly. During cool and humid weather, when the tank is low, it gets moist leading to the oxidation of the tank and formation of rust. This rust is usually ingested by the pump itself, causing the entire system to collapse.

Fuel filter issues

The quality of fuel that you are using in your vehicle will also play a major role in getting the best performance from the fuel pump. A clogged filter is considered to be the worst enemy of the device as it can create low pressure and low peak flow of fuel that weaken its functioning. The reason why this problem is considered to be alarming is because a clogged filter can cause severe damage to the hardware installed in your fuel pump. Clogged filters are generally associated with damaged fuel line connectors/splits or cracked hoses or kinked fuel lines that lead to leakage of fuel. These cracks or leaks on the fuel lines can create vacuum leaks, which disturb the air-fuel ratio, thus, making the engine run lean.

Low fuel levels

If you have a habit of running your car on low fuel levels frequently, chances are its fuel pump will have been severely damaged by now. Low fuel levels cause the tank and consequently the fuel pump to overheat, thereby causing lack of lubrication in the engine, causing severe damage.
