My friends dad jump starts it and we are off. I get to my house and we chill, when its time for him to leave, my car wouldn't start again. This time I get my neighbor to jump start it, and we are off. We get to his house, I drop him off and I went home. The following morning comes, I get into my car and it wont start again, security light isnt on and no lights were working. I check the battery and there were no loose cables or anything, it was completely dead. That same day, I take it to pepboys to have it checked, and they tell me that its dead and that I can recharge it for $5, I said ok. He tries to recharge it and it wouldn't recharge.... he said it was to "hot", whatever that means... I said fine, I'll just buy a new battery. He looks up my car and he takes out the right battery for my car, I noticed right away that the battery I had was much smaller than the one he sold me. I get home and I take a look at the space provided for the battery and it was a perfect fit. Now, I'm thinking that the owner that had it before installed a random battery that wasnt even the right size and slapped it on (I bought the caddy at an auction like 8 months ago). I install the battery and I notice that the security light comes on and the little red light on the dashboard also came on. I try starting the car and it doesn't want to stay on, it cranks, but the accelorating needle just falls all the way at zero when it was idling at 1 when the car would start fine. I just really hope its not the alternator... It also needs an oil change and a tune up right about now so once I get it to start I will take it to the mechanic shop to do that. I need help trying to get it started though, any help would be greatly appretiated. Thanks!
