Re: 2010 cranks but won't start
When you push the pedal to the floor it goes into clear flood mood. So if it starts when you do this I would think that your car is flooding. Maybe bad FPR that is leaking when it sits, I know there was an issue like this with the impalas a few years back. You should be able to take the vacuum hose of the FPR while it's running and it might take a few minutes but if it is leaking you should smell or see fuel. But if it will start when you push the pedal to the floor I would be checking for things that would cause a flood situation.
