It has nothing to do with your starter my friend. If your turn the key and all the lights come on, but no crank, thats not your starter, especially if you have changed it twice!! Good rule of thumb, 99% of the time. If you here 1 click, it's the battery. If you here multiple clicks, it's your starter solenoid, of course this is all while turning the key in attempt to start your car. Why?? Well when your turn the key, your battery sends a pulse of electricity to your starter solenoid so your starter gear will turn. If you here 1 click, and no more, that means pulses arn't getting to your starter, meaning the problem lies within the battery and respective connections. If it's multiple clicks, that means that your starter solenoid is receiving the electricity, but not engaging the starter gear, which means the problem lies within the starter. Open your hood, You have two cables, a ground(black) and positive(red). Follow the cables to their places and make sure they arn't loose. What you need to do next is take them off your battery, and use a steel brush and clean your battery ports, just scrub that shit clean, next scrub the inside of the battery connections, make sure their clean and shiny as well. Next bolt those suckers on TIGHT. I hope this helps you and the other fellow. Good luck!
