i can't seem to find the fuel pump relay location on my 89 beretta can someone help me

You probably already found this answer, but, it is on the firewall. On my 91 Corsica(very similar, in fact Berettas and Corsicas use the same service manuals) on mine it is the fourth relay(far right) in a bank in the middle of the firewall. Mine has a small fuse that looks like a relay that mounts over top of it as well. Yours should be pretty similar if not the same. Had to replace mine this evening because of a random non start and code 54(low voltage to pump). Can always sneak a peek at a Haynes manual when at Advance too, to be sure...
