How do you know if you need to replace a fuel pump on a 1999 Chevy Suburban?

Turn the key to the on postition without starting the truck. You

should hear a buzzing sound in the rear of the truck for approx 3-5

seconds. If you do not hear anything, it's either the fuel pump or

the fuel pump solinoid which is located in the fuse box under the

hood. Does the truck start?
