my 91 std has been sitting for about 5 months after an un succesful mpfi swap. so i redid it and im sure its right but when i tried to start it there was a buzzing noise that came from a relay to the left of the under dash fuse box. what relay is this? does the buzzing mean its blown?

 

Main fuel relay. Controls the fuel pump. Buzzing may be a noise that's gone or on the way out, does the fuel pump still kick in?

Main relays die alot in our cars, they were redesigned, and you can go to honda and pick up the newer ones.
