Three days ago the car would crank but would not start. Eventually i got it started by turning the key back and trying again. Then yesterday it did the same thing however took a little more coaxing this time. I managed to get it started and get a new tank of gas. It got home then this morning it will crank but not start. I disconnected the battery in hopes that it would clear any computer codes, reset the Fuel pump shut off switch and it still won't start. Anyone have any suggestions?
