The starter is the largest electrical draw in the vehicle. Even if all the lights are bright, and everything else works, if there is a marginal connection at the battery, there will not be enough voltage for the starter to come in. If you have a volt meter, you could perform a voltage drop test by connecting the meters ground to the vehicle ground, and probe the starters heavy gage wire with the meters positive wire while you crank the vehicle. If the voltage drops much below 12V, you have a connection problem.If you have positively eliminated the possibility of a bad connection, the starter could be bad/shorted, which would have to be removed and bench tested.
