i have a 2004 mustang gt v6 40thyr edition convertible. It has a brand new battery. I have been driving this car and finally parked it in my garage for about 2 month with the battery unplugged. I accidentally bought a new battery so I put the new one in and started the car. (Triee) it cranked over but immediately shut off like it is not getting gas. Now it keeps cranking, all systems are on, but it just won't start. Checked the fuel shut off switch, but it has not been activated so that isn't it. I'm completely confused what it could be now.
