Car wouldn't start replaced battery and it started right up. I didn't drive it until 2 days later started right up got to the store a few blocks away and it will not start, was told it was the starter so i replaced it and it s still not starting!!

Probably the alternator, when you replaced the battery it had a full charge and once the vehicle used all that charge up and it wasn't charging it could no longer start the car anymore. If your battery light is on in the car it is a fairly certain sign that the alternator is not charging. Generally an AVR test is the best way to check the alternator, but if you can jump start the vehicle, connect a voltmeter to the battery it should be around 14 volts when the vehicle is running and around 12 volts when the vehicle is not running. If it is not at 14 volts when it is running, it is not charging.
