EDIT: Also! If your battery is DEAD jumpstarting wont help it! It takes about 400amp to charge a battery I believe jumpstarting is around 30 give or take. Unless your left it hooked up for about a hour.
Ok, please understand what I'm saying - this is temp related. The battery has nothing to do with this issue. When the outside temp begins to warm up, the car starts first hit, no hesitation. When it doesnt start I have full battery power to everything else, just not to the starter.
I'm guessing that no one has ever had this problem. I'll keep researching. Thanks for trying
Could be the cold is affecting the starter relay. Or solenoid, not sure which one GPs have.
If your battery is DEAD a car jumpstart will not start it right off hand. It takes awhile to charge it up off of a car/truck. Or so it did on a 99 mustang! The battery was DEAD hooked it up to another car it took 30min just for the lights in the inside to barley come on.
jumpstarting had no effect. Something is interupting power to the starter.
