|Loss of current or low voltage
Electric pumps can’t run without electricity obviously, so if anything prevents voltage from reaching the pump, the pump will stop working. Check the wiring to see if it is loose, broken or corroded.
Debris in the tank can build up and clog the strainer, accelerate wear and tear, or cause the pump’s check valve to stay open. This can lead to hard starts due to loss of pressure when your car’s engine is turned off. Be sure to check your tank and keep it thoroughly cleaned in order to prevent failure.
Corrosion in the tank will produce rust that will flake off and plug up the strainer. Rust equally damaging effects as dirt. Rust forms in tanks due to condensation during cool or humid weather when your fuel tank is low. Keep your fuel tank full in order to minimize the formation of condensation that creates rust.
|Normal wear and tear
Electric pumps use the fuel to keep lubricated and cool, which maintains its function and prolongs its lifespan. Frequent driving with low fuel may occasionally starve the fuel pump for lubrication and cooling. Any pump will fail with enough wear and tear.
