Default odd sound from 91 gt

i have a 91 gt all original , it has approx. 130,000 miles on it . very good solid dependable driver. my question is , there is a buzzing or humming sound that comes from the rear of the car as soon as it it started. you can hear it pretty loud from outside , and if you are at an idle you can hear it from the inside also. could this be the fuel pump ??? thanks !!

The fuel pump is easily heard. It starts as soon as you turn the key from the off position. It will run for two seconds and then stop if you don't start cranking it.

^^^no the pump is not stuck!! sometimes as they get older they make some noise, you can try replacing it to see if it quiets down, mine is quiet, but then again it's a newer walbro 255lph
