It could very likely be corroded/dirty battery posts. Sometimes my chevy s10 will not start, and you wait a few seconds, turn the key on n off and it'll start, I'm just too lazy to clean the battery <img src="/forums/images/graemlins/smile.gif" alt="" />

Is the starter getting any voltage when you try and start?

Do the radio and dashlights come on when you put the key into the start position but don't try and start it? or is that intermitent?
