Can a fuel pump drain the battery?
A: The only way the fuel pump could be draining the battery is if the fuel pump is running full time. And it would drain the battery within a few hours, not a week. A normal car battery has 48-64 ampere-hours of capacity, while a fuel pump draws, depending, 6-10 amps.
What causes a fuel pump to not start?
As far as I know, if your fuel pump runs continuously with the key on, engine not running, or not being cranked, the problem is in one of three places. 1. the FP relay is stuck/fused ON.
How does the fuel pump work in a car?
The fuel pump is a device that moves fuel from your tank to the engine, supplying the fuel at a constant pressure to ensure that your engine runs smoothly.
How long does it take for fuel pump to shut off?
Not to mention it just adds more wear and tear to the starter motor and engine. This usually lasts around two or three seconds, unless the ignition key is turned to crank the position.
Why does my fuel pump feel like it is surging?
Irregular resistance inside the fuel pump motor may cause vehicle surging, and indicates a fuel pump in need of repair. Surging feels like the gas pedal has been used. However, it occurs at a random, consistent speed.
