0 views

Fuel pump failure can result from several factors including contaminated fuel, overheating, low fuel levels, and electrical issues. Contaminated fuel can clog the pump, impairing its functionality. Overheating occurs if the pump works excessively without adequate fuel, which lubricates and cools it. Low fuel levels force the pump to work harder, shortening its lifespan. Electrical issues like a faulty relay or wiring problems can prevent the pump from operating correctly.
