It is a normal for a GM fuel pump to hum with some age. However if it goes along with your symptoms it may be bad. It is in the tank so make sure you have an empty tank when you have it fixed. Good Luck

Suggested Repair

A GM fuel pump can hum with age, but humming plus hard starting and stalling suggests the in-tank pump may be failing. Have it checked or replaced with the tank empty.

Conversation Summary

The owner of a 1994 Cadillac Eldorado reported a loud hum near the gas tank, followed by hard starting, stalling, and extra cranking to restart. The expert said some hum is normal on an aging GM pump, but with these symptoms the in-tank pump may be bad and should be serviced with an empty tank.
