Starting problems
 

First off Where is the starter motor located on a 91 V6?? This is stupid Ive been working on cars for at least 25 yrs . But I cant see it DUH !!
Now the problem is Some times it will start right up Other times it just clicks / If I click it a few times it will start!The Batt is fully charged,I changed the Batt terminals on the battery side Still does the same thing!! When it starts the motor cranks just great I am at a loss
Please Help If ya can!!!
