Where is fuel pump relay located

The relay is either located in the large fuze box under the hood, when u locate this fuze box open it and under the cover it will have a picture of where the relay is in the box, or its located on the fire wall under the hood on a rack with a couple of other relays. hope this is helpful please rate me

Look at Autozone.com at the relay for the picture. there are two identical relays on a rack mounted on the drivers side of the firewall in the engine compartment. the one closest to the driver side fender is the fuel pump relay. for trouble shooting you can swap the relays and start the blazer. if it runs unplug each relay one at a time and you know you have the fuel pump relay plug when it dies. if you get stranded you can swap the relays to drive to a store or safety
