I dont have any power running to the intank fuel pump on my 89 full sized blazer.Does anyone know where the fuel pump fuse is located?

 

if you still have the owners manual it is in their if not cant help but you can take every fuse out untill you find it it is a pain but it works

 

I believe it is under the hood on the drivers side wheel well. small black box with a plastic wing-nut in the middle.
under the lid is a diagram... I believe

 

sounds right if it is not there it is one of the relays in the cab
