i own a 94 honda accord vtec i have had it since it was new . i drove it to work the other morning an stayed for 5 hours came back an it would not turn over . i jump started it an drove it home i noticed the abs light stayed on an there was a strange clicking coming from the dash . sount like when your battery is dead an you try to engage the starter . i bought a new alternator cause i thought it may have not been carging the battery i cahanged it an the problem still is there. i also changed the battery when i jump it off an it is running fine i turn the head lights on or the air the abs light comes on an the clicking starts what could be the reason it won't start

 

Are your battery terminals corroded at all? That would be my guess.
