Q: Can a fuel pump drain my battery?

asked by on

Can fuel pump drain the battery?

My car has 83000 miles.

As you may know, the fuel pump does in fact receive power from the battery, however it is highly unlikely that the fuel pump would continue to run when the power to the car is off causing the battery to drain. If this does in fact happen, this would also presumably cause even bigger problems due to the amount of fuel that would be continuously pumping as well. I would recommend having an expert from YourMechanic come to your location to take a look at your battery to determine what may be causing it to drain.
