So here's the deal.. I bought an 08 Dodge Avenger off of a buddy and shortly after buying it, the battery would need jumped in order to get it to start. Summed it up to just be a bad battery. But, the other day I went out to start it up and it kinda sorta started but then died. When I attempted to crank it over again, I got nothing.. BUT everything else is still working fine. When turning the key to start it all the of the lights on the dash come on ( As all vehicle dash lights do). Except now once the lights go back off, the red light on the dash gauge area, continues to flash repeatedly. I thought it might have been tripped when iump starting it but, thought it was strange how it initially attempted to start.. I tried a few of the DIY basic tricks but still no luck. I'm no mechanic so I try to get help from my friends or family that are but this one has even them stumped. Plz give me some feedback so I can (Hopefully) start driving it again. Thank you.
