Car will only start with a jump. Took car to Autozone had the battery,alternator and starter checked all came out good but still will not start without a jump. Any ideas?
It could be a loose terminal connection. Battery terminals can be loose or corroded causing low power. Enough to run but not to crank. Check for looseness & corrosion But even if not looking corroded I would clean them. Terminals can be bought for around $6 in auto parts stores & for less in a department store.
