My husband is a delivery driver for a pizza place, and he went out to start the car for a delivery and it would start, but it would die instantly. When he finally got the car to start and stay that way, he noticed that it is overheating while he is driving. I'm not much with cars, but I want to know if there is anyone out there who might know what is wrong with this car before I take it to someone and have it fixed and we get fleeced. Does anyone know what could cause this?
