Well, I know the battery will need replacement at some point because it's cracked, but if it's not causing the problem at the moment, I can't afford to replace it. I was going to pull it out tomorrow and have it checked at the auto part store. I'd think if it was a bad battery it wouldn't want to crank, but maybe it's just bad enough to where it can't handle any load from the motor? That sounds silly to me.

I had thought the car had a bad o2 sensor or cat from the symptoms it's been having, since I already replaced the MAF, but they said everything was fine. I don't know if they checked any of the fuel related stuff. Tonight just totally caught me off guard, it was running perfectly fine all day. I need to know how to check if that module is bad in the box beside the battery where the ECU is. I heard you have to open it up and look carefully at a certain part of it. Sounds very delicate and touchy to mess with. Perhaps it could be something with the fuel pump as well, just too many possibilities.
