Starting Prob's

Its a 95 S-10 PU, w/ a 4.3L engine and a standard trans. My problem is that nothing happens when i turn the key... at first the lights would dim and there would be a low buzzing coming from the lower left dash.. now nothing happens when i turn the key.. they battery is fully charged, but i have no idea what it could be.. any help would be wonderful.

It could be that the starter has some loss wring or maybe just shot did you have problems before this with it starting?
i had the same problem with my 84 camaro 2.8L it just took a new starter to fix it

i have had problems with the starter because it would spin but it would not engage to the flywheel... after about 10-15 times trying to start the truck it would catch and then start, but would a loose wire on the starter cause all of my lights to not come on?

Sounds like you need a starter anyway. Sometimes when going bad they can make it seem like a bad battery.

Well it turns out im just stupid.. one of the battery cables were loose and corroded enought for a little bit of juice to go through and power the lights but not the starter... thanks everyone..
