1988 Ford Ranger Problem

Everytime I turn the key to turn it over it makes a loud buzzing noise. At first I thought it was the battery so I replaced it. It worked for about a day or so and then it did it again. So I listened to where it was comming from and it is right on the cylanoid. So I replaced that and it still does it. I then thought it could be the starter. So I had it tested and it was fine. So I thought it could be the wiring but I really hope it isnt, that could take forever. Maybe something isnt hooked up right? Not enough ground ire? Maybe its something else? If anyone has any thoughts or ideas I could use them. Thanks

Check all the wires at the starter,the battery and silnoid for bad connection. Green or wight corrosion. Check ground wires at the engine and battery.

Does the buzzing go away? It should last about 2 seconds.....
I think it is just the fuel pump priming the system.(totally normal)

mine does this too so let me know if this is not what it is.....
