2002 Camry Intermittant start issues

[leakyseals]

All of a sudden my gfs 2002 Camry XLE I4 wouldn't start yesterday. Not even a click. Last fall the battery was replaced because it wouldn't start. After a while it started so i went to Autozone to have it tested. Had to turn it off. The battery was fully charged 100%, I looked at the results myself. They cleaned the posts and connections, even tried jumping it, wouldn't start. I should have taken over at that point, they didnt make much of an effort to secure the jumper cables. The other vehicle did seem to go under load when they tried to jump start it so I assume they had it connected ok. After a few minutes, it started on its own, but slow, as if the battery was down. like a hard turn over. Oils good. So its sitting now as it cant be trusted.

Likely the starter, but would a failing starter turn over slow/hard?

i changed the cabin air filter the day before. Is there anything in the area of the cabin filter that i could have loosened? There were cables that were dangling, I had to lift them out of the way.

it could simply be the battery terminals or the cables.... i had this same problem with a previous pos caravan i had and a friend's lexus...... replaced the cables on tha van and the terminals on the lex and they were good as new

Was the starter. Had me fooled. was turning over real slow as if it was the battery.
