My dad recently brought a 93 sts for me with 140k on it. Ive had the car about 3 weeks and one day i came home and parked. Well later on in the day i came back out to go somewhere and the car wouldnt start. The car wont even try to turn over. I know its not the battery as we tried another one. All the accessories come on like there supposed to but the car does nothing when i try to start it. The only thing i noticed is that the gas gauge goes all the way to empty when i turn the key to start it but the car has gas in it. Ive also had the key tested it that wasnt the problem. The screen at the bottom doesnt give me any messages either so i dont know what else to do.
