i have a 1990 toyota supra turbo hardtop and it has a knock so i let it sit in the garage for about 2 months and today i went in to start it up so i can pull it out the garage and work on it.. but when i went to crank it the car wouldnt even turn over or even try to make an attempt... when i turn the key i dont hear any clicking or sounds of attempt.. its completely dead.. i then tried to jump it and nothing either... can someone help me?? im thinking its the starter but not sure.. last month i started it and it didnt have a problem... could it be because of bad gas or low on gas?? i might pull the starter out today and look at it.. but can someone give me thoughts on whats wrong?? can it be my motor is gone ? lol thanks for all ur help
