Does fuel pump affect 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 to do if your car wont start after replacing the fuel pump?
Car won’t start even after I replaced the fuel pump. Car won’t start and turned off while driving. Replaced the fuel pump and I can hear it working. The car still won’t start.
What could be causing fuel pumps to die so quickly?
About 6 months later, the main pump died and was replaced. 6 months after that, the new lifer pump started overheating and died again and was replaced again. Now, about a year later, that new, 3rd lifter pump has died and fried the relay. Would anyone know what could be causing these to die so quickly?
Can a fuel pump be placed upside down?
If that flow is restricted it is a double whammy – the pump is working harder and there is less fuel flowing to cool it. Since most injection systems return unused fuel to the tank a fuel flow restriction might not be noticed. Regarding your battery terminals, check to see if they could possibly be installed upside down.
How does an electric fuel pump keep cool?
Electric fuel pumps run continuously with your engine, delivering high-pressure fuel to the fuel rail and injectors. Fuel pumps keep cool by staying submerged in fuel. If you make a habit of running your tank all the way to empty before filling up; your fuel pump will most likely die before its designed lifespan.
