A faulty Fuel Pump can, however, be the cause of a car battery draining and even equip it working improper or regularly. Electric fuel pumps are intended to switch on with the ignition and suck juice in order for keep any pressure of gas inside a car’s system. A bad fuel pump may either run all the time or draw additional power to operate as desired which in turn raises its electrical needs and strain on your battery. A bad pump can pull 50% more current than a healthy one per tests run. Loading up the battery too much over time will lead to premature failure in it as well.
A failing fuel pump will not keep the pressure high, it can vary but is usually somewhere between 30–80 PSI. If the pump has to work particularly hard here then it could theoretically be ‘on’ for longer than necessary, drawing more power and therefore draining your battery quicker! On the Initial D1, the engine stalls and starts hard as a by-product of poor fuel pump performance. Drivers will repeatedly try to start a stalled engine, and this extra work can drain the battery over time.
And a poor pump also can create more resistant fuel lines, which means the delivery device has to work harder. In the process, fuel pump could be on all of the time; in vehicles where this approach has not been factored against it can waste power. Automotive experts also highlight that if a fuel pump is drawing more energy regularly, the battery may discharge in just one or two days especially if you did not use your vehicle.
The age of the battery is also a consideration. A car battery is usually good for 3 to 5 years before it starts losing capacity. This can put undue load on the battery in an aging system, leading to its demise and perpetuating a cycle of crap. Now you might need to pay the price of a new fuel pump and battery, which could easily be from $400 – $800 or more depending on vehicle.
Preventative maintenance is key. You will not only avoid the pump and battery being over-strained, but also it may well prevent clogs from occurring or at least you’ll pick up wear before any damage happens. Automotive technician Scotty Kilmer warns, “Fail to heed early warnings and a fuel pump in trouble can leave you stranded next time. Never ignore the fuel pump and battery, as conducting regular inspections prevent it from aging down vehicle performance. If you believe that the fault should be in a fuel pump than, Fuel Pump has high-quality replacement solutions customized to match your vehicle’s needs.
