So I've got this project and since I've had her shed start run strong but having alot of issues cranking. I've jumped battery twice now cause once she gets hott she won't start up again without jump im guessing not enough battery juice for the higher compression from it being heated butnd while doing so I would get faint cranks like some to none to weak i can hear the starter trying and now recently instead of starting she will start a second and die out that's if I get her to crank. Ignition switch battery fuel? Maybe all the above I've worked on alot of firebirds but this ones feisty just need some advice. Also she had aftermarket alarm that kept tripping and wouldn't shut off but I removed it recently that's when she would start but shut off second after? Thanks in advance for your time.
