I have a 2003 Hyundai Sonata that been sitting up for almost 6 months nothing was wrong with it when I parked it but now it won't crank what could be the issue and how could I get it to start
possibly try jumping it. if not try the alternator.
Take out the battery and have it recharged and tested, if it tests bad replace it and then see if you engine will crank, but before you attempt anything check the fluid levels, oil, coolant, etc. if it was due for an oil change or even close, change the oil and filter before attempting to start it so all that crud can get out before the engine is even cranked.
