All freeze plugs for engines are below the spark plug side of the engine. They are small round plugs that will pop out if engine freezes in the winter time. This will cause water leaks if they go bad anytime.
I believe that the fuel pump for the 94 Pontiac sunbird is in the gas tank.

Pontiac didn't introduce the Sunfire until 1995, so you may be thinking of a Sunbird.
Well, Pontiac didnt make a sunfire in 1994 is it a 95 sunfire or 94 sunbird?
Did you try the horn relay? It is located near the fuse box.
Listed under the hood on a placard and in the owners manual.
Under the hood, on the lower drivers side, inside radiator support.
I don't know about a 93, but my 94"s is located at the exhaust manifold, just below the spark plugs. You have to remove the wire first, then use the same type of socket you'd use to remove a spark plug.
