04 Starting problem.

So about a month ago I started having problems starting my truck. It would turn over slow or just click. After a few attempts I can get it started. End up cleaning the battery terminals grounds and starter connections and replacing the battery. It worked for about a month. Now its doing it again.

Ill got to start it and itll click once. Got it up to advance check battery alternator and starter and everything checked out good. When I got to start it and it clicks once I get a buzzing sound from the top side of the motor. When the key is in the on position. cant pin point where its coming from though.

Any ideas what to do next?

 

Buzzing sound is probably the electronic throttle. Mine does it. You may have bad contacts in the starter. They're pretty easy to change.
