Chevrolet Cavalier fuel pump intermittent issue, works only 1 out of 40-50 tries after replacement on Chevrolet Cavalier

Some Chevrolet Cavalier owners report experiencing intermittent fuel pump issues, where the pump only operates 1 out of 40-50 attempts after replacement. This problem may be attributed to low voltage, as some owners find the fuel pump receiving only 9.6 volts while cranking the engine, which is insufficient for effective operation. Additionally, electrical faults such as loose connections, faulty wiring, or a malfunctioning fuel pump relay can disrupt the power supply, contributing to these intermittent failures. Clogged components, including the fuel pump impeller or fuel filter, may also restrict fuel flow, causing the pump to function erratically. Furthermore, some owners discover internal leaks within the fuel pump, which can result in weak performance despite adequate fuel delivery under certain conditions, potentially due to leaky hoses inside the tank. To resolve these issues, it is advised to check the voltage supplied to the fuel pump, inspect and secure all electrical connections, consider replacing clogged components, and investigate any internal leaks.
